'Lo.

I just tried to compile the vanilla GNAT-GPL 2009 sources today and
came across the following error:

The actual GNAT part of the compiler appeared to compile without issue, using
the compiler from the lang/gnat-gcc44 port. The above, however, seems to be
a problem with the GCC core. It looks very i386 to me...

There doesn't appear to be any explicit support for FreeBSD amd64/x86_64
in those GCC sources as far as I can tell and not being very familiar with
the GCC codebase, I'm not sure how much work it'll be to add them.

Any ideas?
