 * Everybody does wait() differently.  There seem to be no definitions
 * for this in V7 (e.g. you are supposed to shift and mask things out
 * using constant shifts and masks.)  So fuck 'em all -- my own non
 * standard but portable macros.  Don't change to a "union wait"
 * based approach -- the ordering of the elements of the struct
 * depends on the byte-sex of the machine.  Foo!
