I decided to upgrade from 20090124 snapshot to 0.6.0 release today, and noticed the netbsd fixes I proposed were checked in, so tried using it, yet there would be a "NO-OP" build error of some kind, which wouldn't occur if I re-evaluated the require form at repl, but then an assertion failure would occur in SB-C about a SIGNED-32 type.
I looked again at the source and noticed the fix for netbsd wasn't applied the same as I had applied it on my tree. I had kept :pointer for the udata kevent structure rather than :intptr_t. I thus tried the same on 0.6.0 and it works fine.
I propose the attached diff. Thanks,
