The commit on 2004.5.10 against src/lib/libc/stdio/fparseln.c breaks crossbuilds
on (at least) FreeBSD and IRIX systems:

I haven't tried crossbuilding from a netbsd host.

The resulting error during a "tools" build is:

I've tried on sgimips, hp300, vax, sparc and sparc64 crossbuilds on FreeBSD 4.x and 5.x 
on both i386 and alpha hosts.

Is this perhaps a mod-in-progress that hasn't been fully committed yet?
