Seven months later, I'm finally doing that (in part, because I've re-synced 
glibc getopt over to gnulib, so now the testsuite failure would be on all 
platforms where getopt is replaced, and not just those with modern glibc, the 
moment I pull in the latest gnulib).

(It's a shame my m4 hacking time has been cut short lately, due to all my other 
fun hacking on gnulib)
