Hydra, a continuous integration system, runs Guile's "make check" with
threads disabled on several POSIX platforms, so there's no need for
Panicz to do this test.

Thanks for looking into this, Eli!

This raises the question: what's the relevant difference between
Panicz's simple 'main' and Guile's 'main' (in libguile/guile.c) that
causes one to (apparently) initialize the stack base properly, where the
other fails?  It would be worthwhile to find out.

    Thanks,
