/* Tell that garbage collector that setjmp is known to save all
registers relevant for conservative garbage collection in the jmp_buf.
Not all the architectures are tested, but there are Debian packages
for SCM and/or Guile on them, so the technique must work. See also
comments in alloc.c concerning setjmp and gcc. Fixme: it's
probably safe to just let the GCC conditional in AH_BOTTOM handle this.
