Subject: [PATCH] [project @ 2000-03-18 15:37:58 by panne] Due to
 PrelException_PutFullMVar_static_closure there is a
 circular dependency between libHS and libHSrts, which is
 broken during the linking phase by mentioning -lHS again
 *after* -lHSrts. Hmmm, perhaps it would be better to
 mention the smaller -lHSrts twice instead? With this patch
 4.06 can build 4.07, now let's see if it bootstraps...
