Okay, one more revision, to actually check if the -+ registers as an
option or not. This fits the autoconf paradigm of testing for the bug,
even if it is using AC_TRY_RUN. This way, if Sun fixes the problem in a
later Solaris release, we shouldn't need to change anything.
When cross-compiling, I fall back on looking for the odd Solaris decl to
decide whether to use the GNULIB version of getopt or not. If we wanted
to be really pessimistic, we could always use the GNULIB getopt when
cross-compiling, but I thought this could wait at least until we get a
report of similar behavior from some system other than Solaris 10.
Matthias, would you mind testing this version out? If you could send me
your config.log when you are done building, that would be helpful as well.

* m4/getopt.m4: Check for Solaris 10 bug, not decl, when possible.
Cheers,
Derek
