So far I haven't found any binaries for NetBSD-2.0/sparc64.  I might have
to tap you for that information on cross-compiling.

Actually I don't care which version of gcc-3 it is.  What I'm trying to do
is make use of an U2 system that I have, by utilising it for doing gcc-4 builds
from the gcc cvs tree.  At least something "unofficial" for now, and once I am
familiar with things enough make it a contribution to the GCC folks as well
as the NetBSD pkgsrc folks.

Looking in pkgsrc, the dependencies for gcc3-ada and gcc34-ada are completely
wrong.  According to those dependencies, all you need is gcc and glibc.  There
is no dependency on gnat/Ada itself.  Of course I know better :)

So you compile on some other platform (a NetBSD platform obviously), creating
a whole cross-compiling toolchain, then using the cross-compiling toolchain,
you build the compilers, move them over to target system (netbsd-sparc64),
and then probably just for kicks, use the cross-compiled binaries to generate
the native binaries.  Did I get the jist of it correct ? 

I've not cross-compiled before, but could I build on a solaris-sparc system
so that I can run on a netbsd-sparc64 system ?  I don't have any other
netbsd-sparc64 systems nor any other netbsd systems.

I'll ping you and let you know whether I need it or not.  It sure as heck
would make life easier if gnat was written in C :)  It could then go to any
platform that GCC goes to without worrying about anything too much.
