This patch is incomplete. If gnulib cannot use __nonnull in
getopt_{core,ext}.h, then there is no point trying to define it in
getopt_cdefs.h. And you're going to need to put snippet/arg-nonnull
back in the module file for this to work at all, aren't you?
>From glibc's point of view, I think it would be better if
getopt_core.h and getopt_ext.h simply assumed _GL_ARG_NONNULL to be
available; we can add it to either our getopt.h wrapper or to
sys/cdefs.h - I don't want to make that call unilaterally. (Do you
know of a complete list of _GL_ macros that may appear in _public_
header files?)
