<sys/ioctl.h> wont compile when installing CUPS, whatsup

[pythagras]

Yeah, Im trying to REcompile cups (as in I just compiled this last week), and it appears that my ioctl.h file wont compile I get these warnings from the configure script:

--BEGIN
checking sys/ioctl.h presence... yes
configure: WARNING: sys/ioctl.h: present but cannot be compiled
configure: WARNING: sys/ioctl.h: check for missing prerequisite headers?
configure: WARNING: sys/ioctl.h: proceeding with the preprocessor's result
checking for sys/ioctl.h... yes
--END

Then when I run "make" I receive:

--BEGIN

--END

In looking at my ioctl.h header, this is (some) of what I see. It seems odd because there are identifiers that appear to be undefined, and no precompiler directives to include any other headers..

--BEGIN
#ifndef _I386_CHECKSUM_H
#define _I386_CHECKSUM_H


/*
* computes the checksum of a memory block at buff, length len,
* and adds in "sum" (32-bit)
*
* returns a 32-bit number suitable for feeding into itself
* or csum_tcpudp_magic
*
* this function must be called with even lengths, except
* for the last fragment, which may be odd
*
* it's best to have buff aligned on a 32-bit boundary
*/
asmlinkage unsigned int csum_partial(const unsigned char * buff, int len, unsigned int sum);
-- END

I am running RH 8.0 i686.

Any help or pointers would be apreciated.
