I encountered the very same problem when building the netbsd-1-6 branch
last night too.  However my build is running on an older 1.5W kernel
which also happens to have "options NEW_PIPE".

I smell a very nasty pipe() bug.  Back to using an MFS TMPDIR for me, at
least until I can bootstrap up onto a newer kernel.

Now I thought I did have '-O2' included somewhere appropriate, but it
seems not....  (which would explain why my libc grew bigger too!  ;-)
