A safe starting point would be to:

1. Rename G__tempfile() to G__tempfile_in_mapset().
2. Add:
	char *G__tempfile(int pid)
	{
		return G__tempfile_in_mapset(pid);
	}
3. Change opencell.c (and anything else known to require the existing
behaviour) to use G__tempfile_in_mapset() instead of G__tempfile().

Once that's done, any new G__tempfile() implementation can easily be
reverted if it's found to cause problems.
