Does gcc currently have precompiled headers?  I thought that was something
that would appear with gcc 3.0

Slower than gcc??  Boy, that's slow.

This doesn't really suprise me since gcc doesn't produce particularly
great code for Intel processors.

Is icc code being integrated into gcc?  I guess in the meantime speed
critical sections or a project could compiled with icc and linked in
with the rest (using luvverly C wrappers where necessary, of course).
