From 862b45026fa67277a554eb329538a7d536311eca Mon Sep 17 00:00:00 2001 From: Rical Jasan Date: Mon, 19 Feb 2018 04:37:16 -0800 Subject: manual: Update _DEFAULT_SOURCE. [BZ #22862] The description of the interplay between feature test macros and compiler options in the description of _DEFAULT_SOURCE is a little confusing, and dated, so clarify the situation, and don't assume a specific value for _DEFAULT_SOURCE. Also, _DEFAULT_SOURCE is supposed to be defined if none of the C/POSIX feature test macros are defined, but the condition was lacking a test for _ISOC11_SOURCE, so that is also addressed. [BZ #22862] * include/features.h: Add _ISOC11_SOURCE to test for whether to define _DEFAULT_SOURCE. * manual/creature.texi (_DEFAULT_SOURCE): Improve documentation. --- include/features.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include') diff --git a/include/features.h b/include/features.h index 137a90b..d22c32e 100644 --- a/include/features.h +++ b/include/features.h @@ -214,7 +214,7 @@ define _DEFAULT_SOURCE. */ #if (defined _DEFAULT_SOURCE \ || (!defined __STRICT_ANSI__ \ - && !defined _ISOC99_SOURCE \ + && !defined _ISOC99_SOURCE && !defined _ISOC11_SOURCE \ && !defined _POSIX_SOURCE && !defined _POSIX_C_SOURCE \ && !defined _XOPEN_SOURCE)) # undef _DEFAULT_SOURCE -- cgit v1.1
