/usr/bin/cc  -v
Using built-in specs.
Target: amd64-undermydesk-freebsd
Configured with: FreeBSD/amd64 system compiler
Thread model: posix
gcc version 4.2.1 20070831 patched [FreeBSD]

Well, it might be that I did something in a hurry, that's why I
restarted the whole build.
What I did, I cleaned the whole obj dir and did a 'make build32' in
/usr/src (to save some time), then I got the exact same failures as when
I started from scratch. Now I tried to find all the headers which the
compiler was complaining about, copied them to
/usr/obj/****/src/lib32/usr/include, finished the compilation stage and
at the linker stage 'ld' complained.

Now I'm waiting for the build from beginning with copied headers to see
what happens.

Np, I should have known that you're all at BSDcan ;)

Thanks,
