Lenard Mollenkopf e442e8376d Add feature test macro _ISOC2Y_SOURCE ... This patch starts preparation for C2Y support in glibc headers by adding a feature test macro _ISOC2Y_SOURCE and corresponding __GLIBC_USE (ISOC2Y). (I mostly copied the work of Joseph Myers for C2X). As with other such macros, C2Y features are also enabled by compiling for a standard newer than C23, or by using _GNU_SOURCE. This patch does not itself enable anything new in the headers for C2Y; that is to be done in followup patches. (For example an implementation of WG14 N3349.) Once C2Y becomes an actual standard we'll presumably move to using the actual year in the feature test macro and __GLIBC_USE, with some period when both macro spellings are accepted, as was done with _ISOC2X_SOURCE. Tested for x86_64. Signed-off-by: Lenard Mollenkopf <glibc@lenardmollenkopf.de>		2024-11-04 22:40:55 +00:00
