A large part of it is fixincludes.  On Solaris we're able to avoid lots of
fixed includes via various schemes -- mostly because the Solaris header
files are pretty close to what GCC needs.  HPUX is a radically different
story unfortunately.

Certainly.  If it wasn't for fixincludes it'd be a hell of a lot easier to
take a compiler built on version of the OS and use it on another.
