System: NetBSD dennis.urc.uninett.no 1.6ZC NetBSD 1.6ZC (DENNIS) #6: Fri Oct  3 14:21:27 CEST 2003  jarle@dennis.urc.uninett.no:/sys/arch/hp300/compile/DENNIS hp300
Architecture: m68k
Machine: hp300
>Description:
	The host is running 1.6ZC.

	I'm using sources from yesterday, and have rebuilt the tools,
	so gcc is 3.3.2 nb1:

dennis# /usr/tools/bin/m68k--netbsdelf-gcc --version
m68k--netbsdelf-gcc (GCC) 3.3.2 (NetBSD nb1 20031026)

dennis# 

	while the host compiler which built the above is 2.95.3:

dennis# cc --version
2.95.3
dennis# 

	While trying to compile a new kernel, the following error was
	encountered:

    compile  DENNIS/igmp.o

*** BUILD ABORTED ***

	The DENNIS kernel is a pruned-down GENERIC hp300 kernel.


>How-To-Repeat:
	Try to build a new kernel from recent sources and with updated
	tools on any m68k-based host (I suspect) which has not yet
	made the leap to gcc 3.3.2.
