Hey Rich!

    Does Symantec have any plans to market an optimizing version of the LSC
compiler?  Developers could use LSC to do the development, then use SSC
(Sound Speed C :-) to produce LSA's (Light Speed Applications).  For those
of us who feel the need for speed, such a product would allow us to stay in
the LSC fold instead of defecting to MPW.
