I'd believe it. Another reason to use 3.0 as the default, if I can make it
work. Sadly, NetBSD still uses egcs 2.91 as it's default compiler, so I have
no idea if we might need 2.95 as a kernel compiler. Hopefully we can get
the kernel patched to be clean for 3.0, if it's not. I guess we'll see.

I have attached the build log from 3.0 at the end.

Linking against libed.a, which provides a regex library, works fine (that's
why I've been able to build ed-dependant packages). The call to regexec comes
back with the pointer passed into it being set to 0xffffffff; this clearly
indicates stack corruption, because nothing else could actually *cause* that.
I don't know what's triggering it, but the end result *shouldn't* be possible
in the first place, if things were compiling and linking right.

Indeed. That would be quite useful. :)
