I have exactly three instances of 'WANT_KERNEL_TYPES' in my
/usr/include tree. :-) I'm honestly not sure why they wern't ripped
out completely unless that is something that was PLD specific that was
slipped in there as it really doesn't hurt. Might want to check
Redhat, Gentoo, Debian, ... sets to see what they do. The quick
solution for xorg-server was to remove both instances of linux/types.h
in lnx_agp.c. I chose to add the same protected ifdef to
linux/types.h and drag in sys/types.h.
I don't see any of these references in sys/types.h, or am I missing
something.
