Another possibility (which came from talking to Stepan Kasal) is that
the code is failing because aux is being inlined.  To avoid this, we
can use instead the find_stack_direction code from Autoconf and
Gnulib, in which find_stack_direction calls itself recursively.

Therefore I've now committed 2 changes upstream which I hope will fix
the current Debian build failures:
http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commit;h=4ff3575c77f95ed5c86970fa93629ba3cfab1912
http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commit;h=9143131b2766d1e29e05d61b5021395b4c93a6bc

If someone from Debian could try these out on all the architectures,
that would be great.
