Hi Andy,

I've tested on a Solaris-9 SPARC zone, with these results:

gmake[4]: Entering directory
`/export/home/andrewg/guile/branches/1.8.8/src/guile-1.8.8/test-suite/standalone'

==================================

This occurs with and without the patch to guile-1.8.8/libguile/threads.c.
Without the patch to guile-1.8.8/libguile/gc_os_dep.c, the build doesn't
even complete:

gc_os_dep.c: In function `scm_get_stack_base':
gc_os_dep.c:1909: error: `USERLIMIT' undeclared (first use in this function)
gc_os_dep.c:1909: error: (Each undeclared identifier is reported only once
gc_os_dep.c:1909: error: for each function it appears in.)

So this patch is good to go, I think.

I've tried debugging the core left behind by test-unwind by rebuilding with -g,
but I get this far, after which I'm stuck:

Core was generated by
`/export/home/andrewg/guile/branches/1.8.8/src/guile-1.8.8/test-suite/standalone'.

(gdb) p to

I'm pretty sure this is not due to the patch to guile-1.8.8/libguile/threads.c,
since it happens with and without it.
