C2x makes static_assert and thread_local into keywords, removing the definitions as macros in assert.h and threads.h. Thus, disable those macros in those glibc headers for C2x. The disabling is done based on a combination of language version and __GNUC_PREREQ, *not* based on __GLIBC_USE (ISOC2X), on the principle that users of the header (when requesting C11 or later APIs - not assert.h for C99 and older API versions) should always have the names static_assert or thread_local available after inclusion of the header, whether as a keyword or as a macro. Thus, when using a compiler without the keywords (whether an older compiler, possibly in C2x mode, or _GNU_SOURCE with any compiler but in an older language mode, for example) the macros should be defined, even when C2x APIs have been requested. The __GNUC_PREREQ conditionals here may well need updating with the versions of other compilers that gained support for these keywords in C2x mode. Tested for x86_64. |
