System: NetBSD stegg.urc.uninett.no 1.6ZK NetBSD 1.6ZK (STEGG.MP) #3: Fri Feb 20 02:22:55 CET 2004  he@stegg.urc.uninett.no:/usr/obj/sys/arch/i386/compile.i386/STEGG.MP i386
Architecture: i386

>Description:
	Host system is 1.6ZK/i386, target is 2.0C/pmppc.

	Briefly looking at a scrolling build log for a powerpc-based
	port I had not cross-built yet, I saw the attached error
	messages scroll by while gcc3's backend configure script was
	running.  Surely, this can't be healthy for the result?

	Apparently the configure script assumes that the tools should
	be in $PATH, which doesn't appear to be the case.  They are in
	my $TOOLDIR, though.
