Subject: provide NSIG under _BSD_SOURCE (default) as well as _GNU_SOURCE
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=7dcb640da361f272a6c317b03466fd2013934c81

provide NSIG under _BSD_SOURCE (default) as well as _GNU_SOURCE

this fixes a regression related to the changes made to bits/signal.h
between 0.9.7 and 0.9.8 that broke some (non-portable) software.
