On 64-bit targets, the register_t type must be a 64-bit integer.

Add u_register_t definition for FreeBSD comptatibility.

Is RTEMS the only case in newlib that provides register_t?

No, this is why I moved the definition to <machine/types.h>.

Can you fix this for Cygwin as well in the same patch?


Thanks,
