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.

/* How this works:

 Fdump_emacs dumps everything up to my_edata as text space (pure).

 The files of Emacs are written so as to have no initialized
 data that can ever need to be altered except at the first startup.
 This is so that those words can be dumped as sharable text.

 It is not possible to exercise such control over library files.
 So it is necessary to refrain from making their data areas shared.
 Therefore, this file is loaded following all the files of Emacs
 but before library files.
 As a result, the symbol my_edata indicates the point
 in data space between data coming from Emacs and data
 coming from libraries.
