Help compiling on 2.4.25

I have upgraded my kernel to 2.4.25 thinking this would solve my problem but
it did not go away ...

When I try a "make clean modules" on the latest cvs tarball I get the
following error:

....
gcc -D__KERNEL__ -I/root/src/linux-2.4.25/include -Wall -Wstrict-prototypes

Can someone help?

Thanks,
