As discussed before, shared libraries on Mac OS X can not reference the
environ variable directly, where applications can. This is a show
stopper on Mac OS X, because of the internals of autoconf and because
the environ variable is referenced in gpc's runtime library. To solve
this problem, I apply the following patch:
--- gcc/p/rts/rts.c.orig Wed Apr 16 01:58:46 2003
+++ gcc/p/rts/rts.c Fri Jun 6 11:35:50 2003

I would be grateful if this patch is merged with gpc's sources.
