Re: gcc precompiled headers

A couple years ago, I tried and tried to get PCH to work with C++ and
never figured it out. That was pre gcc-4, though. Things may have
improved now.

But really, ROM doesn't take long at all to compile on modern hardware
and I don't think using pch would result in any significant gains.
