'gcc' is the compiler driver. There'll be a gcc included in the GNAT
distribution - that's the one it wants.

I've had trouble before with the 'checking for a compiler driver that
understands Ada' code. The easiest thing to do is use the GNAT-supplied
compiler as the bootstrap compiler - it should support both C and Ada - and
ignore any other gccs you've got. Put the GNAT bin directory first in your
path and fingers crossed it'll all work.

I've also have had trouble with the gnatlib and tools not installing
properly; make sure when you're done you have a
<prefix>/lib/gcc-lib/<target>/<version>/adalib and adainclude, and that at
least gnatbind and gnatmake are in <prefix>/bin. I think I had to butcher
the makefiles a bit and install a few things manually. But then maybe that
was user error - I didn't read the docs :-)

Good luck,
Rup.
