From 42cc619dfbc44e263239c2de870bae11ad65810a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 1 Feb 2024 11:02:01 +0000 Subject: Refer to C23 in place of C2X in glibc WG14 decided to use the name C23 as the informal name of the next revision of the C standard (notwithstanding the publication date in 2024). Update references to C2X in glibc to use the C23 name. This is intended to update everything *except* where it involves renaming files (the changes involving renaming tests are intended to be done separately). In the case of the _ISOC2X_SOURCE feature test macro - the only user-visible interface involved - support for that macro is kept for backwards compatibility, while adding _ISOC23_SOURCE. Tested for x86_64. --- NEWS | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'NEWS') diff --git a/NEWS b/NEWS index 39a55f5767..2d8eaffc58 100644 --- a/NEWS +++ b/NEWS @@ -14,6 +14,13 @@ Major new features: in order to support unsigned __int128 and/or unsigned _BitInt(N) operands with arbitrary precisions when supported by the target. +* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to + enable features from the ISO C23 standard.
