AC_USE_SYSTEM_EXTENSIONS enables _XOPEN_SOURCE, _GNU_SOURCE and similar macros to expose the largest extent of functionality supported by the underlying system. This is required since these macros are often limiting rather than merely additive, e.g. _XOPEN_SOURCE will actually on some systems hide declarations which are not part of the X/Open spec. Since this goes into config.h rather than the command line, ensure all source is consistently including config.h before anything else, including system libraries. This doesn't need to be guarded by a HAVE_CONFIG_H ifdef, which was only ever a hangover from the X.Org modular transition.
