On a related note, looking at the code in os_dep.c, it appears that
these two constants are only used when HPUX_STACKBOTTOM is defined; I
think their definition should be removed from the "ifdef LINUX" clause
in gcconfig.h.

Looking at misc.c, it seems that GC_register_stackbottom is only set
when '(defined(LINUX) || defined(HPUX)) && defined(IA64)', so it will
remain equal to zero on FreeBSD.
