I managed to bootstrap the 3.0 branch (20010402) with

	CC='cc -xarch=v9' configure sparcv9-sun-solaris2.8
	make bootstrap
	make RUNTESTFLAGS='--target_board "unix{-m32,}"' check

You need to apply

	http://gcc.gnu.org/ml/gcc-patches/2001-04/msg00250.html

(still unreviewed) for the -m32 tests to succeed, but with this setup, -m32
and -m64 testsuite failures are almost the same.  I still have to post a
complete analysis of the differences I encountered, but the 64x32 cross
compiler seems to work resonably.

Unfortunately, that's not what I really want: we won't be running 64-bit
Solaris 2.8 on all our machines, so either I need two different
installations of gcc: one sparcv9 for 64-bit (and 32-bit if desired)
compilation, and another sparc for 32-bit compilation.  Just having the
bi-arch 32x64 compiler instead of those (as Sun's cc does) would be much
more convenient.
