compilation error in coreutils-6.9 source code.

[Michael]

When trying to build coreutils-6.9 on debian 5.0 amd64, it fails because of 
duplicate function name:

function futimens exists in utimens.h and sys/stat.h and they are not 
compatible. This bug is supposed to be caused by the system headers.

Details:
