I accidentally ran 'make check' in Gnulib (wrong terminal window), but
it ended up being useful. I saw:
File lib/options.h lacks a config.h reminder. Needed for: _GL_GNUC_PREREQ
File lib/stdcountof.in.h lacks a config.h reminder. Needed for:
_GL_GNUC_PREREQ
This is correct since lib/gnulib-common.m4 will emit a _GL_GNUC_PREREQ
definition in config.h. We must include it before these headers so it is
defined.
Done with the two attached patches.
