 In rts/PosixSource.h various standards and extensions are enabled.  This
 yields in sys/types.h on Darwin *not* defining u_* typedefs.  The code
 however relies on this.  This problem has been noted already, and hence a
 hack to define _DARWIN_C_SOURCE has been added which works on Darwin 9 and
 up.

 On Darwin 8, however, this define doesn't exist in sys/types.h.  Without
 wanting to change the u_*, I resorted to the rather hackish fix as
 attached, such that sys/types.h is included on Darwin before various
 standards are set, and hence the u_* types will disappear.
