Salut!, amis français! (Und auch sonst so, natürlich.)
POSIX has recently standardized a NSIG_MAX constant in <limits.h> [1]:
The value of {NSIG_MAX} shall be no greater than the number of signals that
the sigset_t type (see [cross-ref to <signal.h>]) is capable of representing,
ignoring any restrictions imposed by sigfillset() or sigaddset().
I'm personally following an advise of Rich Felker in the meantime:
#ifdef NSIG_MAX
# undef NSIG
# define NSIG NSIG_MAX
#elif !defined NSIG
# define NSIG ((sizeof(sigset_t) * 8) - 1)
#endif
That is for "old" signals only, there; maybe reducing this to
#undef NSIG
#ifdef NSIG_MAX
# define NSIG NSIG_MAX
#else
# define NSIG ((sizeof(sigset_t) * 8) - 1)
#endif
should do the trick for Python on any POSIX system?
Ciao from, eh, gray, Germany :)
