This is the only thing left that uses it.

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

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.
* Activate.c (XMenuActivate): Callback's first arg is readonly.
* AddPane.c (XMenuAddPane): Label is readonly. Rename local
to avoid shadowing.

* Create.c (atoi, atof): Remove decls; include <stdlib.h>.
(MAX_INACT_PNUM, TILE_BUF_SIZE): Remove; unused.
(x_get_resource_string): Args are readonly.
(XAllocDisplayColor): colorName is readonly.
(XMenuCreate): def_env is readonly. Remove unused locals. Avoid
"else;".

(_XMRefreshSelection): Return void.
(_XMWinQueFlush, _XMRefreshSelection): Rename locals to avoid
shadowing.
(_XMWinQueFlush): Use stack, not heap. Don't use uninitialized var.
* SetAEQ.c (XMenuSetAEQ): Now returns void.
* SetFrz.c (XMenuSetFreeze): Likewise.

* XDestAssoc.c, XMakeAssoc.c: Likewise.
* XDestAssoc.c (XDestroyAssocTable): Return void.
* XMakeAssoc.c (XMakeAssoc): Use void * for generic pointer.
* XMenu.h, XMenuInt.h: Adjust to signature changes. Use const
for pointers to readonly storage.
* insque.c: Include XMenuInt.h, to check our own signature.
(emacs_insque, emacs_remque): Use void * for generic pointers.
* configure.in (C_WARNINGS_SWITCH, PROFILING_CFLAGS)
(PROFILING_LDFLAGS): Substitute, don't add them to CFLAGS/LDFLAGS.

* src/Makefile.in (C_WARNINGS_SWITCH, PROFILING_CFLAGS)
(PROFILING_LDFLAGS): Set from substitution.
(ALL_CFLAGS): Add C_WARNINGS_SWITCH and PROFILING_CFLAGS, put
CFLAGS last.
* Makefile.in (C_SWITCH_SYSTEM): Use @C_SWITCH_SYSTEM@ rather than
@c_switch_system@.
* oldXMenu/Makefile.in (C_SWITCH_SYSTEM, C_SWITCH_MACHINE): Use
@C_SWITCH_SYSTEM@, @C_SWITCH_MACHINE@ rather than
@c_switch_system@, @c_switch_machine@.
