SOCK_DGRAM should definitely be visible.  Most likely it's yet another 
case of kernel header breakage, since those headers haven't changed at 
all (to the best of my knowledge) in klibc at all.

The ARCH_HAS_SOCKET_TYPES is there to let an architecture override the 
global kernel define, which is a major reason why moving this into the 
klibc headers is a bad idea.

What kernel and platform is this?
