-current build problems on AMD 64

["Niall James O'Higgins" <njo_(_at_)_sig11_(_dot_)_com>]

Hi all,

We've got a new dual opteron machine with an ahd SCSI controller which
we want to run root raid on.

So we installed -current snapshot from 3rd Aug to an ATA disk, hoping
to use that to make release.

We fetched the latest -current source tree from AnonCVS 
following the instructions in the documentation, and built a GENERIC.MP 
kernel with ahd and raid enabled.

The kernel compile went flawlessly, but when I run 'make build' in
/usr/src, the compile bombs out while compiling gcc.

I paste the compile output & error below:

cd /usr/src/gnu/lib/libf2c/../../usr.bin/gcc &&  make -f
Makefile.bsd-wrapper config.status tree-check.h
`config.status' is up to date.

If anyone has any pointers or the developers need more information, I
will do my best to supply it.

I have built i386 snapshots quite recently without a problem so I was
surprised when I hit this issue with amd64.

Thanks in advance,
