dnl prereq_module is a module (without the "mod_" prefix) that must be enabled
dnl if the current module is enabled. If the current module is built
dnl statically, prereq_module must be built statically, too. If these

dnl APACHE_ADD_GCC_CFLAG
dnl
dnl Check if compiler is gcc and supports flag. If yes, add to NOTEST_CFLAGS.
dnl NOTEST_CFLAGS is merged lately, thus it won't accumulate in CFLAGS here.
dnl Also, AC_LANG_PROGRAM() itself is known to trigger [-Wstrict-prototypes]
dnl with some autoconf versions, so we force -Wno-strict-prototypes for the
dnl check to avoid spurious failures when adding flags like -Werror.
