[Buildroot] Bug 171 - vm86.c error: IF_MASK undeclared

I just ran into this problem, and worked around it by updating the  
patch file (below) so it points to the right files, and putting it in  
my package/x11r7/xserver_xorg-server folder.

That said, I was wondering if there's a different fix, some package  
or header I'm missing or something, since it seems like a fairly old  
problem.
