I should mention we are running Linux 2.4.16 or so,
using gcc3.0.2 (gcc2.9.7 from Montavista had same problem on sh4),
and we configured once for target powerpc-unknown-linux-gnu
and in a different copy of the tree for sh-unknown-linux-gnu.

Thanks very much to Daniel J. and Montavista for contributing
these patches.  We're really looking forward to using them.
