I think it's a lot more plausibly a mistake for mq_attr than for timespec 
(and thus a lot more plausible that a future POSIX version might add 
typedefs here), since as far as I can tell valid values for these fields 
could exceed the width of long, but they clearly can't for tv_nsec.  
(Though it's arguably similarly a mistake that printf functions return 
int, with a consequent limit on the number of bytes output.)
