When compiling GNU emacs with Sun's std. `cc' on a SPARC running 4.0
(or 4.1 for that matter), is it safe to specify standard optimization,
namely -O, for the compilation?  Someone here states having seen on
the net, that if optimization is performed then only -O1 should be
done and that -O, which implies -O2 on a SPARC, is dangerous for GNU
Emacs. 

Can someone in the know reply?  If others might be interested I could
summarize to the followup ng (gnu.emacs).  Thanks!
