OK, so it's HAVE_LIBC_STACK_END that is not defined, then?  When this
is the case, 1.8 leaves scm_init_guile undefined, whereas 1.6 would
use the vast pile of magic in gc_os_dep.c.

Does that sound right?  If it is, I wonder why the change was made to
remove the gc_os_dep.c fallback option; I can't see anything obvious
in the ChangeLog.  (gc_os_dep.c and the necessary scm_get_stack_base()
definitions are still there in 1.8, they're just not used.)
