bootstrapping problems with native compiler

Yes.  It's a problem, partly a g77 issue, and partly a library issue
as you've noticed.

g77 won't build with any compiler except gcc.  Odds are it'll be a while
before that restriction is lifted -- until that point we need to make
sure it's not built as part of a "make bootstrap".  Patches for this
would be greatly appreciated.  Or if people want to start fixing the
g77 front end to be compilable by non-gcc compilers, that would be
appreciated too.

And, as you found out (as did I) there's a circular dependency related
to cplib2.txt.
