RE: <signal.h> on HP-NonStop

My fix for NSIG:
diff -u ./gllib/signal.in.h.orig ./gllib/signal.in.h

 #if @GNULIB_SIGPROCMASK@
-# if address@hidden@

 /* Maximum signal number + 1.  */
 #  ifndef NSIG


And reg. SA_RESETHAND and SA_RESTART: yes we're  behind the current POSIX by 
quite a bit unfortunatly. 
And if I read 
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/signal.h.html 
correclty, these have been optional up to Issue 6.

Bye, Jojo

Hi Bruno

OK, the highest number for any SIG<something> is 31, so NSIG should really be 
32.

The only SA_<something> Macros I can find are SA_DATA_SITE in <sys/socket.h>, 
most probably unrated, and SA_NOCLDSTOP and SA_RESERVED_31 in <signal.h>, and 
nothing that looks remotely like a replacement, signal.h attached

Bye, Jojo

Hello Joachim,

Please, let's use different mails with different subject for each topic.
Otherwise I cannot keep track which issues have been dealt with, and the 
conversation dies down in confusion.

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 <signal.h>.

And the definition belongs in <signal.h>.

These two are specified by POSIX
<http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/signal.h.html>.
Does NonStop Kernel really lack these flags, or are they merely available under 
different names?
