Actually, the replacement function is not needed. But the piece of
configure.ac from modules/gethostname is expanded into configure in all
cases. And it sets GNULIB_GETHOSTNAME=1 unconditionally.

Then it needs to be (@GNULIB_GETHOSTNAME@ && address@hidden@), and
your gethostname.m4 file needs to set a HAVE_DECL_GETHOSTNAME variable.

Anyway, it needs more prerequisite work regarding the modules 'sockets',
'errno', 'strerror'.
