You are probably not doing anything wrong, but rather have been bitten
by a bug in the gcc installation in netbsd-1.4.1. I know that nested
functions doesn't work for arm32 either (and I think it is broken for
68060 processors too.) I fixed it for arm a long time ago, but never
got around committing it...

I'll try to take a look at this before we ship NetBSD-1.5...

Gcc didn't build out of the box for NetBSD/pmax last time I checked. I
have promised I'll fix that before the next gcc release.
