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.

| 779 an XBM file, a 1 bit is foreground, and a 0 bit is | |
| 780 background. | |
| 781 | |
| 782 XCreatePixmapCursor() assumes this property of the | |
| 783 pixmap it is called with as well; the `foreground' | |
| 784 color argument is used for the 1 bits. | |
| 785 | |
| 786 With an XPM file, it's tricker, since the elements of | |
| 787 the pixmap don't represent FG and BG, but are actual | |
| 788 pixel values. So we need to figure out which of those | |
| 789 pixels is the foreground color and which is the | |
| 790 background. We do it by comparing RGB and assuming | |
| 791 that the darker color is the foreground. This works | |
| 792 with the result of xbmtopbm|ppmtoxpm, at least. | |
| 793 | |
| 794 It might be nice if there was some way to tag the | |
| 795 colors in the XPM file with whether they are the | |
| 796 foreground - perhaps with logical color names somehow? | |
| 797 | |
| 798 Once we have decided which color is the foreground, we | |
| 799 need to ensure that that color corresponds to a `1' bit | |
| 800 in the Pixmap. The XPM library wrote into the (1-bit) | |
| 801 pixmap with XPutPixel, which will ignore all but the | |
| 802 least significant bit. | |
| 803 | |
| 804 This means that a 1 bit in the image corresponds to | |
| 805 `fg' only if `fg.pixel' is odd. | |
| 806 | |
| 807 (This also means that the image will be all the same | |
| 808 color if both `fg' and `bg' are odd or even, but we can | |
| 809 safely assume that that won't happen if the XPM file is | |
| 810 sensible I think.) | |
| 811 | |
| 812 The desired result is that the image use `1' to | |
| 813 represent the foreground color, and `0' to represent | |
| 814 the background color. So, we may need to invert the | |
| 815 image to accomplish this; we invert if fg is | |
| 816 odd. (Remember that WhitePixel and BlackPixel are not | |
| 817 necessarily 1 and 0 respectively, though I think it | |
| 818 might be safe to assume that one of them is always 1 | |
