This isn't anything to do with your change, but -qversion should be
moved to the second position in this list, because the AIX compiler's
response to any unrecognized command-line option is to dump its _entire
manpage_ to stdout, which is IIRC about 10,000 lines of text. I see
that _AC_DO_LIMIT clips to ten lines by default, so we're not gonna get
a ridiculous amount of junk in config.log, but it would still be more
efficient to have it closer to the beginning (I only suggest we put it
second because it's far more likely that the user actually has a
compiler that understands --version).
