From 769fd4ce202225ba1f2621bbefb803ee9a268ebf Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Mon, 3 Dec 2012 16:57:01 -0500 Subject: feature test macros: make _GNU_SOURCE enable everything previously, a few BSD features were enabled only by _BSD_SOURCE, not by _GNU_SOURCE. since _BSD_SOURCE is default in the absence of other feature test macros, this made adding _GNU_SOURCE to a project not a purely additive feature test macro; it actually caused some features to be suppressed. most of the changes made by this patch actually bring musl in closer alignment with the glibc behavior for _GNU_SOURCE. the only exceptions are the added visibility of functions like strlcpy which were BSD-only due to being disliked/rejected by glibc maintainers. here, I feel the consistency of having _GNU_SOURCE mean "everything", and especially the property of it being purely additive, are more valuable than hiding functions which glibc does not have. --- include/signal.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/signal.h') diff --git a/include/signal.h b/include/signal.h index 89080ab6..b24f43a5 100644 --- a/include/signal.h +++ b/include/signal.h @@ -212,7 +212,7 @@ void (*sigset(int, void (*)(int)))(int); #define NSIG _NSIG #endif -#ifdef _BSD_SOURCE +#if defined(_BSD_SOURCE) || defined(_GNU_SOURCE) typedef void (*sig_t)(int); #endif -- cgit v1.2.1
