fix compile issues with gcc 4
-------------------- ChangeLog entries follow: --------------------
ChangeLog addition:
2010-01-24 Ben Wing <ben@xemacs.org>
* aclocal.m4 (XE_SHLIB_STUFF):
Use -export-all-symbols instead of -export-dynamic on PE targets
(Cygwin and MinGW).
* configure.ac (XE_EXPAND_VARIABLE):
* configure.ac (TAB):
Create variable XEMACS_CC_GPP to check whether we're running g++.
Don't just check for an executable called `g++' -- it might be
called g++-4 or whatever. Instead, check for either named `g++*'
or claiming to be g++ when called with --version. Rewrite code do
use the variable.
Add -fno-strict-aliasing to optimization flags when GCC and
optimized, and in all cases with g++, since under these circumstances
strict aliasing is otherwise assumed, and XEmacs can't easily be
made to respect its restrictions.
* configure: Regenerate.
lib-src/ChangeLog addition:
2010-01-24 Ben Wing <ben@xemacs.org>
* fakemail.c (args_size):
* fakemail.c (parse_header):
* ootags.c (C_entries):
Fix warnings about possible use of uninitialized vars.
lwlib/ChangeLog addition:
2010-01-24 Ben Wing <ben@xemacs.org>
* xlwgauge.c (GaugeResize):
* xlwgauge.c (GaugeSize):
Fix warnings about possible use of uninitialized vars.
modules/ChangeLog addition:
2010-01-24 Ben Wing <ben@xemacs.org>
* postgresql/postgresql.c (CHECK_LIVE_CONNECTION):
* postgresql/postgresql.c (print_pgconn):
* postgresql/postgresql.c (Fpq_connectdb):
* postgresql/postgresql.c (Fpq_connect_start):
* postgresql/postgresql.c (Fpq_exec):
* postgresql/postgresql.c (Fpq_get_result):
Fix g++ 4.3 complaints about implicit conversions of string
literals (const char *) to char *.
src/ChangeLog addition:
2010-01-24 Ben Wing <ben@xemacs.org>
* chartab.c (decode_char_table_range):
* extents.c (extent_fragment_update):
* objects-msw.c (initialize_font_instance):
* process.c (Fgetenv):
* redisplay-output.c (get_next_display_block):
Fix warnings about possible use of uninitialized vars.
* compiler.h:
* compiler.h (REGISTER):
* event-stream.c (is_scrollbar_event):
* window.c (window_scrollbar_width):
* window.c (window_scrollbar_height):
* window.c (window_left_window_gutter_width):
* window.c (window_right_window_gutter_width):
Add USED_IF_SCROLLBARS. Use it to fix warnings about unused
vars when --with-scrollbars=no.
* config.h.in:
Change comment to explain better why DECLARE_INLINE_HEADER
is needed.
* dialog-msw.c:
* emacs.c (SHEBANG_EXE_PROGNAME_LENGTH):
* emacs.c (main_1):
* event-msw.c (struct mswin_message_debug):
* event-msw.c (debug_output_mswin_message):
* font-mgr.c:
* font-mgr.c (Ffc_config_filename):
* glyphs-msw.c (struct):
* glyphs-msw.c (bitmap_table):
* glyphs-x.c (update_widget_face):
* intl-win32.c (struct lang_to_string):
* intl-win32.c (lang_to_string_table):
* nas.c:
* objects-xlike-inc.c:
* objects-xlike-inc.c (xft_find_charset_font):
* syswindows.h:
* win32.c (mswindows_output_last_error):
Fix g++ 4.3 complaints about implicit conversions of string
literals (const char *) to char *.
* lisp.h:
G++ 4.3 needs #include <limits> to avoid errors about min/max.
* lisp.h (disabled_assert_with_message):
Use disabled_assert* whenever asserts are disabled. Rewrite
disabled_assert* to avoid complaints about unused vars by
pretending to use the vars but casting them to (void).
Remove code that defined assert() weirdly if DEBUG_XEMACS but
not USE_ASSERTIONS -- configure sets USE_ASSERTIONS automatically
when DEBUG_XEMACS, and if the user has forced it off, then
so be it.
* lisp.h (SYMBOL_KEYWORD):
Put some of the combined `extern Lisp_Object's back under
the file they are declared in. Cosmetic fix.
* number.h:
Remove `extern Lisp_Object' decls that duplicate lisp.h,
since they have different C vs. C++ linkage.

line source
The files in this directory contain source code for the core XEmacs facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc files are byte-compiled versions of the corresponding *.el files. Byte-compiled files are architecture-independent. Functions used only by files in this directory are considered "internal" and are subject to change at any time. All commands, and most functions with docstrings, are part of the exported API. In particular, it is considered good style to use the Common Lisp facilities provided in cl*.el. (Yes, that's ambiguous. Sorry, we don't have a full specification of the API, as the Lispref is chronically incomplete. Anything described in the Lispref is part of the API, of course.) Libraries which implement applications and enhancements are placed in the "packages", which are distributed separately from the core sources. #### Someone please update this. #### Partially updated 2001-08-25 by sjt. Needs more work. Mike? When XEmacs starts up, it adds certain directories in various hierarchies containing Lisp libraries to `load-path' (the list of directories to be searched when loading files). These are: this directory, its subdirectory ./mule (in Mule-enabled XEmacs only), the site-lisp directory (deprecated), and all the lisp/PACKAGE subdirectories of the xemacs-packages, mule-packages, and site-packages hierarchies. See setup-paths.el. #### Is the following true or relevant any more? bogus> Directories whose names begin with "-" or "." are not added to bogus> the default load-path. Some files which you might reasonably want to alter when installing or customizing XEmacs at your site are: paths.el You may need to change the default pathnames here, but probably not. This is loaded before XEmacs is dumped. site-init.el #### obsolete and removed? To pre-load additional libraries into XEmacs and dump them in the executable, load them from this file. Read the instructions in this file for a description of how to do this. site-load.el #### description is obsolete This is like site-init.el, but if you want the docstrings of your preloaded libraries to be kept in the DOC file instead of in the executable, you should load them from this file instead. To do this, you must also cause them to be scanned when the DOC file is generated by editing ../src/Makefile.in.in and rerunning configure. #### new semantics This file will preload additional libraries listed in ../site-packages and dump them into XEmacs. ../site-packages List of additional libraries read by site-load.el. site-start.el This is loaded each time XEmacs starts up, before the user's .emacs file. (Sysadmin must create.) Can be inhibited for a given invocation with `--no-site-file'. default.el This is loaded each time XEmacs starts up, after the user's .emacs file, unless .emacs sets the variable inhibit-default-init to t. (Sysadmin must create.) Can be inhibited for a given invocation with `-q'. version.el This contains the version information for XEmacs. ======================================================================== Original text follows: The files in this directory contain source code for the XEmacs facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc files are byte-compiled versions of the corresponding *.el files.

The only files which remain at top-level are those which you might reasonably want to alter when installing or customizing XEmacs at your site.
