+2007-05-18  Francesco Potortė  <pot@gnu.org>
+	* etags.c: Extern definitions of some more pointer functions for
+	standalone compilation, especially important for 64bit platforms.
+	(main, print_help): --members is now the default for etags.
+	(C_entries): Parse start of C comment as a space == end of token.
+	This is not necessary for C++ comment, already parsed as newline.
+2007-02-05  Francesco Potortė  <pot@gnu.org>
+	* etags.c (default_C_help, Cplusplus_help, PHP_help, print_help)
+	(main): Now --members is the default for etags, not for ctags yet.
+2007-01-02  Francesco Potortė  <pot@gnu.org>
+	* etags.c (longopts): New undocumented option --no-duplicates.
+	(no_duplicates): Static variables for the above option.
+	(print_help): Do not print help for --no-warn, now undocumented.
+	(add_node): Allow duplicate tags in ctags mode unless --no-duplicates.
+	(main): Pass the -u option to sort in ctags mode.
+2006-12-28  Francesco Potortė  <pot@gnu.org>
+	* etags.c (readline): When creating a relative file name from a
+	#line directive, leave the file name alone.  The previous
+	behaviour was to make it relative to the tags file directory,
+	under the hypothesis that the #line directive file name was
+	relative to the directory of the tagged file.  That hypothesis is
+	wrong with Cpp and Lex.
+2006-12-20  Francesco Potortė  <pot@gnu.org>
+	* etags.c (C_entries): DEFUN names were longer by one: corrected.
+	(Makefile_targets): Do not include spaces in tag names.
+2006-08-12  Kevin Ryde <user42@zip.com.au>
+	* etags.c (readline): Check for double quote after #line.
+2006-08-12  Jan Djärv  <jan.h.d@swipnet.se>
+	* etags.c (readline): sscanf could in principle return 2.
+2006-08-12  Francesco Potortė  <pot@gnu.org>
+	* etags.c (readline): lno is unsigned.
+	(TeX_commands): Use p++ (rather than *p++) to increment p.
+	(Lua_functions): Explicitely discard LOOKING_AT's return value.
+2006-08-07  Masatake YAMATO  <jet@gyve.org>
+	* etags.c (TEX_mode): Check getc retruns EOF.
+	File ended without newline causes infinite loop.
+2002-07-14  Adrian Aichner  <adrian@xemacs.org>  (tiny change)
+	* etags.c: It's XEmacs, not Xemacs: change all the occurences.
+2006-07-10  Francesco Potortė  <pot@gnu.org>
+	* etags.c [ETAGS_REGEXPS]: #ifdef's deleted, define unconditionally.
+	[LONG_OPTIONS]: Changed to NO_LONG_OPTIONS, now normally undefined.
+	(Objc_suffixes): Suggest using --lang=c for full help.
+	(C_entries): Initialise savetoken to 0 to shut up the compiler.
+2006-07-10  Francesco Potortė  <pot@gnu.org>
+	* etags.c (absolute_filename): Free unused space (cosmetic change).
+	(in_word_set): In C, also tag #undef symbols.
+2006-05-02  Francesco Potortė  <pot@gnu.org>
+	* etags.c (Perl_functions): Free space allocated for var package.
+	(Erlang_functions): Possibly free space allocated for var last.
+	(Prolog_functions): Possibly free space allocated for var last.
+2005-11-18  Hideki IWAMOTO <h-iwamoto@kit.hi-ho.ne.jp>  (tiny change)
+	* etags.c (main): Cxref mode writes to stdout: do not close tagf,
+	which was never opened.
+2005-09-27  Francesco Potortė  <pot@gnu.org>
+	* etags.c: Preliminary Forth support.
+	(prolog_pr): Cast strlen to int before comparison.
+	(LOOKING_AT, LOOKING_AT_NOCASE): Let the preprocessor check that
+	the second argument is indeed a literal string.
+	(main): In append mode, sort the tags file after writing it.
+2005-09-27  Emanuele Giaquinta  <emanuele.giaquinta@gmail.com>  (tiny change)
+	* etags.c (longopts, print_help, main): The -a (--append) option
+	can be used in ctags also; for one, the Linux make file uses it.
+2004-09-13  Francesco Potortė  <pot@gnu.org>
+	* etags.c (main): When relative file names are given as argument,
+	make them relative to the current working dir, rather than
+	relative to the output tags file, if the latter is in /dev.

+	* etags.c [EXIT_SUCCESS, EXIT_FAILURE]: Define them when no
+	<stdlib.h> is available.
+	(enum sym_type): New st_C_attribute value for parsing
+	gcc's __attribute__.  Deleted st_C_typespec value.
+	(gperf, in_word_set): Use gperf 3, options changed.  Added the
+	__attribute__ keyword, removed all the st_C_typespec keywords,
+	changed attribute for Java to (C_JAVA & !C_PLPL).
+	(inattribute): New global bool, part of the C state machine.
+	(cblev): Identifier renamed to bracelev throughout.
+	(consider_token, C_entries): Numerous changes for making the
+	parser more robust and adding support for __attribute__.
+2004-09-08  Francesco Potortė  <pot@gnu.org>
+	* etags.c: Add arch taglines

+	[GOOD, BAD]: renamed to EXIT_SUCCESS, EXIT_FAILURE.
+	(suggest_asking_for_help): Fix having macros in a printf statement.
+	(consider_token): check C++ `operator' only when the token len is
+	long enough.
+2003-01-09  Francesco Potortė  <pot@gnu.org>

+	string that cannot be freed.
+2002-08-30  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (consider_token, C_entries): Switch to C++ parsing when
+	auto-detection is enabled and the `::' qualifier is met.
+	(consider_token, C_entries): Several bugs corrected that tagged
+	some declarations even though --declarations was not used.
+	(plainc): New macro.
+	(C_entries): Use it.
+	(C_entries): Several cosmetic changes.
+	(C_entries): Invalidate the token is some cases.
+2002-08-29  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (C_entries): Corrected a problem with const C++ funcs.
+	(ignoreindent): Renamed from noindentypedefs.

+	(pattern): Structure renamed to `regexp', member regex renamed to
+	pattern.
+	(node_st): Member pat renamed to regex.
+	(pattern); New member force_explicit_name, for future use.  Now
+	always set to true, cannot be reset.
+	(add_regex, regex_tag_multiline, readline): Use it.
+	(main): Free some global structures.
+2002-06-21  Francesco Potorti`  <pot@gnu.org>

+2002-06-20  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: Use, together with etags.el, an optimised form of tags,
+	which are almost always unnamed.  etags.el looks for an explicit
+	tag name, then for an implicit one.  See make_tag for details.
+	The change is both forwards and backwards compatible.
+	(make_tag): New function (was the disabled function new_pfnote).

+	(readline_internal): Increment lineno here.
+	(readline): Conditionally undo readline_internal increment.
+	(readline): Do not return a value.
+2002-06-06  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (enum arg_type): New label at_stdin.
+	(STDIN): New constant.
+	(parsing_stdin): New flag.

+2002-05-31  Paul Eggert  <eggert@twinsun.com>
+	* etags.c (main): Use `sort -o TAGFILE TAGFILE' instead of
+	`sort TAGFILE -o TAGFILE', as POSIX 1003.1-2001 disallows
+	the latter usage.
+2002-04-22  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: (last_node): Make it a global variable.
+	(process_file): Print the tags from the nodes as soon as
+	possible, and delete the nodes.  This brings down the memory
+	occupancy as etags to almost the same level as when the #line
+	directives were not parsed.
+	(free_fdesc): New function.
+	(find_entries): Use it.
+	(invalidate_nodes): In etags mode, do not just mark the nodes as

+2002-04-13  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (find_entries): Delete tags previously obtained from
+	file xxx.c's #line directives when parsing file xxx.y.  This is
+	generally done for automatically generated files containing
+	#line directives.  This handles the case when xxx.y is tagged
+	before xxx.c, and the entries of xxx.c pointing to xxx.y should
+	be discarded.
+	(language): Added the metasource member.  Initializers changed.
+	(invalidate_nodes): New function.
+2002-03-21  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (readline): Discard lines after having found a #line
+	directive pointing to an already tagged file.  This handles the
+	case when xxx.y is tagged before xxx.c, and the entries of
+	xxx.c pointing to xxx.y should be discarded.
+2002-03-15  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (fdesc): New structure for keeping track of input files.
+	(fdesc): Remove `file' member (a string) and use instead a pointer
+	to a file description structure.
+	(curfile, curfiledir, curtagfname, curlang, nocharno,
+	forced_lang): Global variables removed in favor of fdhead and
+	curfdp, pointers to file description strucures.
+	(longopts, main, print_help): Use the CTAGS conditional to include
+	or exclude options that work on etags or ctags only.
+	(process_file, find_entries, pfnote, add_node, put_entries,
+	readline): Use fdhead and curfdp.
+	(process_file, find_entries): Do not take an arg string, all
+	callers changed.
+2002-03-13  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (longopts, print_help, main): Test CTAGS to disallow
+	options that are not right for either etags or ctags.
+2002-03-12  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (number_len, total_size_of_entries): Define them also
+	in CTAGS mode, because gcc does not compile all refs away.
+	(Python_functions, PHP_functions): Name tags, for ctags' sake.
+	(TeX_commands): Name tags.  Correction of old disabled code.
+2002-03-06  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (Python_functions): Consider indented "def" and "class".
+2002-03-05  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (curfiledir, curtagfname): New global variables.
+	(process_file): Initialise them.
+	(readline): Canonicalize the name found in #line directive.
+2002-03-05  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: Honour #line directives.
+	(no_line_directive): New global var; set it for old behaviour.
+	(main): Remove some #ifdef in the getopt switch.
+	(add_node, put_entries): Code added to merge different chunks of
+	nodes referring to the same file.  Currently the tags are just
+	appended, without any check for duplicates.
+	(Perl_functions): Do not special case ctags.
+	(readline): Identify #line directives and do the right thing.
+	(nocharno, invalidcharno): New global vars.
+	(process_file): Reset nocharno.
+	(readline): Set nocharno.
+	(pfnote): Read nocharno and maybe put invalidcharno in node.
+	(total_size_of_entries, put_entries): Use invalidcharno.
+2002-03-04  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: Keep the whole tag table in memory, even in etags mode.
+	(main): Call put_entries here even in CTAGS mode.
+	(main, process_file): Check the return values of fclose and pclose.
+	(process_file): Do not call put_entries after parsing each file.
+	(process_file): Canonicalise file names even for ctags.
+	(process_file): Set curfile here...
+	(find_entries): ... not here any more.
+	(add_node): In etags mode, build a linked list of entries (on
+	right pointer) for each file, and link the first entry of each
+	file on left nodes.
+	(put_entries): Print here the name of the file.
+	(put_entries): Print the entries starting from the first file.
+	(number_len, total_size_of_entries): Define these only iin etags
+	mode, make the second work only on the right nodes.
+2002-01-03  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: Make all global variables static.
+2001-12-21  Francesco Potorti`  <pot@gnu.org>

+2001-12-21  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (LOOKING_AT): Use !intoken instead of iswhite.
+	(F_takeprec): Renamed from takeprec.  All callers changed.
+	(F_getit): Renamed from getit.  All callers changed.
+	(nocase_tail): Renamed from tail.  All callers changed.
+	(Ada_getit): Renamed from adagetit.  All callers changed.

+2001-12-17  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: [P_]: Renamed to __P for consistency with config.h.
+	[HAVE_CONFIG_H]: Let config.h deal with __P.
+	[__STDC__] [!HAVE_CONFIG_H]: Define PTR as in config.h.
+	[!__STDC__] [!HAVE_CONFIG_H]: Do not undefine static, because
+	gperf code needs it.
+	[HAVE_CONFIG_H] [!PTR]: Define PTR (for use with Xemacs).
+	[HAVE_CONFIG_H] [!__P]: Define __P (for use with Xemacs).
+	(xmalloc, xrealloc): Use PTR instead of long *.
+	(bool): Make it a define, not a typedef, for C++ compilers.
+	(pattern): Members renamed to avoid name clash in some C++ compilers.
+	(get_language_from_langname): Use const argument.
+2001-12-12  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (PHP_functions): New function by Diez B. Roggisch,
+	heavily adapted by me, for parsing PHP.
+	(LOOKING_AT): New macro.
+	(Perl_functions, Python_functions, PHP_functions)
+	(Scheme_functions, Texinfo_nodes): Use it.
+	(Perl_functions): Use strneq.

+	(prolog_pr): Recognise Prolog rules (thanks to Geert Kloosterman)
+	in addition to predicates.
+	[ETAGS_REGEXPS] [!HAVE_CONFIG_H] [__CYGWIN__]: Prevent
+	unmodified compile, as Cygwin's regex.h is incompatible with us
+	(thanks to Markus Hoenicka).
+	[!HAVE_CONFIG_H] [!__STDC__]: #define const as the empty string.
+2001-05-11  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (add_regex): Reset the whole newly allocated pattern
+	buffer instead of the individual members.  It's safer and works
+	with Xemacs.
+2001-02-23  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (enum sym_type): New label st_C_template.
+	(gperf input): Use it for switching to C++ from C.
+	(consider_token): Do it.
+2001-02-16  Francesco Potorti`  <pot@gnu.org>
+	* etags.c (C_entries): Initialise typdefcblev to quiet compilers.
+2001-02-06  Francesco Potorti`  <pot@gnu.org>
+	* etags.c [!HAVE_CONFIG_H] [!__STDC__]: #define static as nothing.
+2001-01-31  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: [NDEBUG] #undef assert and #define it as ((void)0), for
+	the sake of some buggy assert.h (e.g. in MinGW and sunos4 pcc).
+	(C_entries): Tag token renamed to still_in_token because sunos4
+	pcc wants to expand it as the token() macro even though it has no
+	arguments.
+2001-01-30  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: [WIN32-NATIVE]: #undef MSDOS, #undef WINDOWSNT and
+	#define it for the sake of Xemacs.
+	[WINDOWSNT]: #undef HAVE_NTGUI even if built without
+	HAVE_CONFIG_H.  This change only affects a standalone etags.
+	[WINDOWSNT]: #undef DOS_NT and #define it even if built with
+	HAVE_CONFIG_H.  This change does nothing in Emacs, as DOS_NT is
+	always defined when HAVE_CONFIG_H and WINDOWS are both defined.
+	[!HAVE_UNISTD_H]: use defined(WINDOWSNT) instead of the bare
+	WINDOWSNT, as this is the correct way to use it.
+2001-01-28  Francesco Potorti`  <pot@gnu.org>
+	* etags.c: Be capable to parse nested struct-like structures.
+	(structdef, structtag): Struct state machine revisited.
