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.

14 other changes should be preceded by a comment /* XEmacs change */.

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
21 #define BROKEN_SIGIO. Jamie says:

25 3. All instances of HAVE_GETWD, HAVE_DUP2, HAVE_UNISTD_H, NEED_UNISTD_H,
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
26 HAVE_GETTIMEOFDAY and NEED_REALPATH removed. We detect these
376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14
cvs

30 support X10 or earlier so the HAVE_X11 define was purged.

32 5. Most of the signal crap (e.g. redefining sigsetmask, defining
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
33 POSIX_SIGNALS) has been removed. There are four possible
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
34 signal paradigms that all systems fall into, and we auto-detect
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

35 them in configure and handle them in syssignal.h.

37 6. Removed references to INTERRUPT_INPUT. XEmacs does not use
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
38 this bizarre way of reading input.

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
41 in INTERRUPT_INPUT and in the select() emulator, neither of
376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14
cvs

45 and in FSF Emacs.

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
48 They are unnecessary with the cleaned up syswait.h in XEmacs.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
49 (We autodetect sys/wait.h). Instead, #define or #undef
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

50 HAVE_UNION_WAIT.

52 10. Removed BSTRING. Not used anywhere. (If the header file
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
53 says there are bugs in bcopy() or the like, however, a
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
54 #define BROKEN_BCOPY is added for reference.)

376386a54a3c Import from CVS: tag r19-14
cvs
parents:

57 XEmacs makes consistent use of the ANSI-equivalent
376386a54a3c Import from CVS: tag r19-14
cvs

58 functions memcpy, memset, memcmp, strchr, strrchr.

376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
69 HAVE_TCATTR (when HAVE_TERMIOS was also defined).
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
70 configure detects these and systty.h automatically defines
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
71 HAVE_TCATTR when HAVE_TERMIOS is defined.
