Trouble compiling a simple program

[Todd MacDermid]

Hey all, I appear to be having an issue compiling a simple program
under Fedora Core 1. the program is as follows:

#include <linux/ip.h>
#include <stdio.h>

int main() {

  printf("Foo\n");
  return(0);
}

And attempting to compile it gives me:

[tmacd at bahamut src]$ gcc -g -O2 -Wall -c test.c 
In file included from test.c:1:
/usr/include/linux/ip.h:95: parse error before `__u8'

[tmacd at bahamut src]$ 

This is just an example of a problem that's been keeping me from compiling
a more complex program, which compiled under RH9, but doesn't compile
due to header file problems under Fedora. Is there a prerequisite to
including linux/ip.h, or am I hitting some other issue?

Any insight is much appreciated,

Todd
