Well, I know, the discussion is about C, but in our C++ project
(http://www.mico.org) I see an improvement in a code quality (our
servers/clients perform better) and the code is generaly smaller...
Right, I don't know anything about C.
On the other hand, I don't like gcc slowness at all, but here I'm
optimist.
Cheers,
Karel
