Yes, but didn't actually do it, mostly because I'm not sure Solaris
has exactly the same interface.  It shouldn't be too hard.  I also
thought about using one of the Lisp regex packages.  Never did
anything more than think about it though.

(P.S.  I fixed the bug that made info searches so much slower in clisp
and CMUCL.  It was using * when it should have been \*.  Ah, the fun
of reading someone else's hairy regexps using a different syntax!)

That's already taken care of in the init-maxima routine.

A broken glibc is a good reason to use GNU regex.  If people think
this is worth having, I see no reason why it can't be added as part of
maxima's source, just like gmp has been added.

Probably not too hard as long you're careful in writing the texi
files.  The searches being done are usually fairly simple.  I think
the regexp's just add a bit of robustness when things are quite
what was expected.

At that point, I'd rather have maxima start up a browser to load up
the html version.
