Makefile & configure: add a NO_FNMATCH_CASEFOLD flag
On some platforms (like Solaris) there is a fnmatch, but it doesn't support the GNU FNM_CASEFOLD extension that's used by the jj/icase-directory series' fnmatch_icase wrapper. Change the Makefile so that it's now possible to set NO_FNMATCH_CASEFOLD=YesPlease on those systems, and add a configure probe for it. Unlike the NO_REGEX check we don't add AC_INCLUDES_DEFAULT to our headers. This is because on a GNU system the definition of FNM_CASEFOLD in fnmatch.h is guarded by: #if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 || defined _GNU_SOURCE One of the headers AC_INCLUDES_DEFAULT includes ends up defining one of those, so if we'd use it we'd always get NO_FNMATCH_CASEFOLD=YesPlease on GNU systems, even though they have FNM_CASEFOLD. When checking the flags we use: ifdef NO_FNMATCH ... else ifdef NO_FNMATCH_CASEFOLD ... endif endif The "else" so that we don't link against compat/fnmatch/fnmatch.o twice if both NO_FNMATCH and NO_FNMATCH_CASEFOLD are defined.
