Now that you've fixed this I've run the tests from the latest gnulib
c-stack module on Irix 5.3 with libsigsegv from CVS.
Unfortunately the c-stack tests still fail.

make[4]: Entering directory `/usr/people/tgc/c-stack.test/gltests'
Segmentation fault - core dumped
FAIL: test-c-stack.sh
FAIL: test-c-stack2.sh

I gave it a quick whirl on Irix 6.5 aswell and libsigsegv CVS does not fix
the coredump previously reported. I've got no log from this run but I can
reproduce if necessary.
