From 8a508f301cb9fb7e11f7cc2e3be7ffd42e64c25f Mon Sep 17 00:00:00 2001 From: Yaakov Selkowitz Date: Tue, 4 Jul 2017 18:10:02 -0500 Subject: [PATCH] Cygwin: fix signal.h with _POSIX_C_SOURCE=1 struct sigaction is POSIX.1-1990 but siginfo_t, which is used by its sa_sigaction member, is POSIX.1b-1993. Therefore it needs to be guarded as well, and as part of a union, the struct size is protected.
