Subject: fix broken siginfo_t with _GNU_SOURCE defined
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=03a8362930c3c4fe49ee6b9cb2ba9f28153b15d3

fix broken siginfo_t with _GNU_SOURCE defined

this bug was introduced in a recent patch. the problem we're working
around is that broken GNU software wants to use "struct siginfo"
rather than "siginfo_t", but "siginfo" is not in the reserved
namespace and thus not legal for the standard header to use.
