Uh, have you run gnat's ./doconfig script? That generates a 'doinstall'
script that, amongst other things, renames xgcc to gcc. It also puts all the
binaries in the tree layout that gcc expects. cc1 the backend C compiler and
cpp is a separate C preprocessor.

OK, I've tried this on our sun box: I unpacked it, told doconfig to install
it to gnat315p in my home directory and then I added [...]/gnat315p/bin to
the start of PATH, [...]/gnat315p/lib to the start of LD_LIBRARY_PATH. After
that, it's using the gcc that gnat provide as the main C compiler:

    fox:~/build/323ada$ gcc -v
    Reading specs from [...]/lib/gcc-lib/sparc-sun-solaris2.5.1/2.8.1/specs
    gcc version 2.8.1
    fox:~/build/323ada$ ~/cvs/gcc32/configure
       --prefix=[...]/local/gcc32 --enable-threads=posix
       --disable-checking --disable-nls --with-cpu=ultrasparc
       --enable-long-long --enable-languages=ada
    Configuring for a sparc-sun-solaris2.8 host.
    [...]
    checking for compiler driver that understands Ada... gcc 

which looks OK (and no messing with the ADAC variable!).

After you've configured it, you'll want to follow the ADA instructions on
the GCC site

    http://gcc.gnu.org/install/build.html#TOC3

I've got a bit of time before other people want to use the box so I'll make
sure this all works builds OK (and get back to you if it doesn't).

Good luck,
Rup.
