MPW 3.0 C does support precompiled headers, but they are a
little buggy in the beta version. My compile times went down
by a factor of 8 for a large project!

The new C compiler uses the same basic code generator as
the MPW pascal compiler, so its level of optimization is
reasonably high, though certainly not state of the art.
Benchmarks have shown that the new compiler is slightly
faster on some programs, and slightly slower on others.

By the way, I'm pretty sure the Green Hills Compiler doesn't
contain any PCC code. It was written from scratch (in Pascal!),
many years ago.
