Add release logs.
Regenerate AUTHORS and ldefs-boot.el.

* etc/PROBLEMS: Remove obsolete '#define static' cruft.
* lwlib/xlwmenu.c [emacs]: Include "bitmaps/gray.xbm".
(gray_bitmap_width, gray_bitmap_height, gray_bitmap_bits) [!emacs]:
Remove; all uses replaced with definiens.
* src/s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
This #undef was "temporary" in 2000; it is no longer needed
now that '#define static' has gone away.
* src/xfns.c, src/xterm.h (gray_bitmap_width, gray_bitmap_height)
(gray_bitmap_bits): Remove; no longer needed.
All uses replaced with definiens.
* src/xterm.c: Include "bitmaps/gray.xbm".

This is the only thing left that uses it.

* configure.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.

* src/Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.

* lwlib/Makefile.in (C_SWITCH_X_SYSTEM): Remove.

* oldXMenu/Makefile.in (C_SWITCH_X_SYSTEM): Remove.
(ALL_CFLAGS): Remove C_SWITCH_X_SYSTEM.

* msdos/sedlibmk.inp, msdos/sed1v2.inp:
GNUSTEP_CFLAGS replaces C_SWITCH_X_SYSTEM.

I have been using this change for many months in my private copy
of Emacs, and have used it to find several bugs.  It's mature
enough to publish now.
* Makefile.in (GNULIB_MODULES): Add warnings, manywarnings.
* configure.in: Support --enable-gcc-warnings, in the style of
other GNU packages such as coreutils.
(C_WARNINGS_SWITCH): Remove, replacing with...
(WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable.
(PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I,
when including system files with GCC.
* etc/NEWS: Mention --enable-gcc-warnings.
* lib/Makefile.am (AM_CFLAGS): New macro.
* m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib.
* lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(BASE_CFLAGS): Use new macros rather than old.
* lwlib/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* oldXMenu/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
* src/regex.c: Ignore -Wstrict-overflow.  If !emacs, also ignore
-Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
-Wunused-result, -Wunused-variable.  This should go away once
the Emacs and Gnulib regex code is merged.
(xmalloc, xrealloc): Now static.

This is needed because lisp.h includes intprops.h now.

(make_menu_in_widget): Add cast to avoid warning.

* lisp/progmodes/cc-cmds.el (c-beginning-of-statement): Revert
2011-01-31 change.

XtResizeWidget/XtResizeWindow after XtPopup.  Works better with
Compiz.

resource that specifies helvetica for menus and dialogs.

(mostlyclean): Forget about "core" files.
