NetBSD ultra 2.0_BETA NetBSD 2.0_BETA (GENERIC) #0: Thu May 20 18:40:11 UTC 2004  autobuild@tgm.netbsd.org:/autobuild/netbsd-2-0/sparc64/OBJ/autobuild/netbsd-2-0/src/sys/arch/sparc64/compile/GENERIC sparc64
>Description:
I cross-built the toolchain using today's sources for hp700 on a sparc64 in the hopes of compiling a snapshot of hp700.  It failed with what looked like the same compiler error in several places.

What's interesting is that I had no trouble cross-compiling from MacOS X 10.3.5/Darwin 7.5.8, which is why I'm filing this under sparc64.

I eventually commented out inet6, isp, procfs, and ntfs, and had to give up at kern/init_sysctl.c because there was no appropriate thing to disable to get past the borked file.

If I compile with inet6 commented out, it bails further down at isp:
