However, if I'm reading these headers correctly, FreeBSD does *not*
include sys/types.h in stdlib.h.  (It does include sys/_types.h but I
think that's their equivalent of bits/types.h - nothing but __names.)
Perhaps that is a lower-risk change for us.  I am going to talk to the
people who do Debian archive rebuilds about trying both possibilities.

(If we still had it, this might be an appropriate thing to put under
__FAVOR_BSD, but I see it's gone, and it doesn't seem important enough
to resurrect it for.)
