Paul Eggert b8df54ffbe configure: new option --enable-gcc-warnings ... 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.		2012-04-09 00:45:59 -07:00
