I have a Pentium executable that builds Alpha binaries.  I know the C
and C++ parts work right but I can't link an alpha binary on my pentium if
it's ada.   Then I wanted to cross compile (from pentium generate alpha) an
alpha compiler that generates alpha code.  I just want to see that I can
actually compile ada code before I start trying to build the whole compiler.

Thanks for the tips,  I'll beat on it some more.
