Pulling in the new AM_GNU_GETTEXT macro from gettext 0.18.1 causes
errors with older versions of autoconf, such as 2.59, because
AC_USE_SYSTEM_EXTENSIONS is required but not defined. The requirement
originates in fcntl-o.m4. Maybe it is possible to fallback to
AC_GNU_SOURCE there as is done in threadlib.m4.
