* sigset_t: signal set data structure
* ===================================
*
* Note: There's not much point in trying to copy the
* way this is done in the ILE C header files,
* since RPG doesn't support integers that are
* 1-bit long. Instead, I've defined the mask as
* one big field, and you can test/set bits with
* the %bitand() and %bitor() BIFs
