I have used the attached patch (based on Hans' first suggested patch).

The results are good (however, I happened to throw an an additional
--enable-threads that I know cause troubles on sparc32/linux). 

I'd say the proposed patch works for sparc32, and I know Hans has
a proposed patch for "all" sparc targets that I hope is in the process
of being tested by folks having those arch available.

Here are the not-yet-quite-ready results:

This was on a Debian Woody (test release) sun4m system with these
packages:

binutils                           2.12.90.0.1-1
dejagnu                            1.4.2-1.1
gcc                                2:2.95.4-14 (Debian prerelease)
gcc-2.95			   1:2.95.4-5 (Debian prerelease)
kernel-image-2.2.20-sun4dm-smp     9
libc6                              2.2.5-4

In-tree joined gcc-3.1 and binutils-2.12 cvs branches.

An unofficial patch to boehm-gc/include/private/gcconfig.h is used.
It makes boehm-gc use LINUX_STACKBOTTOM instead of the "old" method.
I assume this patch is to be incorporated in the branch and trunk
soon.
