<sys/select.h> depends on <sys/types.h>...?

IIRC, FreeBSD 5.x doesn't need the extra <sys/types.h> include either. AFAIK, 
it's not so a much wrong-or-right issue (SUSv2 or similar standards don't 
require sys/select.h to setup the types it needs), but just a change of 
conventions (not having to include sys/types.h to make sys/select.h work is 
certainly convenient).

If you go back a few linux kernel/solaris/macosx releases, you'd probably find 
the extra include requirement there, too.
