commit 5b1daf072556c1fc9a00e8735fa0cdba280c2231
Author: Diego 'Flameeyes' Pettenò <flameeyes@gmail.com>
Date: Wed Oct 1 13:26:32 2008 +0200
Fix building on OpenSolaris (without _NSIG definition).
On OpenSolaris, the _NSIG macro is not defined, but NSIG is; as it's
not possible to use NSIG under glibc (it would miss the SIGRT*
series), define a SIGNAL_UPPER_BOUND depending on the system (and
error out if the system lacks both NSIG and _NSIG).
