NSIG should be larger than any predefined signal value. Since you say
that your system has 33 signals, the value 32 is not right. Probably 33,
34, or 64 is better then. You need to look at the values in your

And the definition belongs in <signal.h>.

These two are specified by POSIX
Does NonStop Kernel really lack these flags, or are they merely available under
different names?
