Congratulations Gerard.

I've tried to build GNAT for VMS Alpha from the FSF sources several
times but I never succeeded because various bits appear to be
incomplete or missing for the VMS Alpha target.

I never tried to build an IA64 compiler because I don't have an IA64
box but it's clearly more complete than the Alpha target is (or you
put more work into it than I was willing to do. :-))

What versions of the FSF GCC and binutils source kits did you use ?

How much trouble did you have building gcc against the DEC C headers ?

I have noticed that the DEC C headers required fewer changes in later
versions of FSF gcc in my various build attempts than the earlier
versions did.

Simon.
