Jeff - do you want this redone, changing types.h and SPU machine _types.h?

If so, what should I use for define names? types.h already uses lower case
(like __timer_t_defined), but the other patch I made used uppercase
(__FPOS_T_DEFINED).

i.e. which form of case and underscore prefix: __gid_t_defined,
_gid_t_defined, __GID_T_DEFINED or _GID_T_DEFINED?
