Oh, actually, I see now that configure.in uses the OCTAVE_CC_FLAG and
OCTAVE_CXX_FLAG macros to check for these options, so they could still
be added for non-gcc compilers if those compilers don't complain when
given those options.  I'm not sure how best to handle these kinds of
options, short of using a database, and knowing which compiler you are
actually using, and it seems that doing that is very much against the
spirit of autoconf.
