PATCH 1/1 2.6.0: ioctl related warnings in userspace

Hi,

the patch below (2nd resend) removes warnings like:

warning: signed and unsigned type in conditional expression

when compiling userspace applications against a glibc built with 2.6 kernel headers (like on Debian unstable). Please apply.

Regards,
Johannes
