See, the solution to the crossbuild problem (and to the "non-GCC
bootstrap compiler" problem) is to build cpplib for the build machine,
and wrap a custom tool around it.  That part is easy.  But once
you've done that, why not make the custom tool a little cleverer so
that it can generate _all_ the dependencies?  I don't think it's
hard.
Has anybody considered dropping the requirement of
being able to bootstrap from any C89 compiler?
We just changed from any C compiler to C89 compiler, I would say no.
Now a C99 compiler is a different issue but we should wait until we
implement every part of C99 to get rid of the C89 dependent.
