--- Comment #7 from commit-h...@freebsd.org --- A commit in branch stable/11 references this bug: URL: https://cgit.FreeBSD.org/src/commit/?id=b582d1422b4db6c22ff061a32257a83405d06cc9 commit b582d1422b4db6c22ff061a32257a83405d06cc9 Author: Dimitry Andric <d...@freebsd.org> AuthorDate: 2021-04-08 11:13:15 +0000 Commit: Dimitry Andric <d...@freebsd.org> CommitDate: 2021-04-15 10:24:28 +0000 Avoid -pedantic warnings about using _Generic in __fp_type_select When compiling parts of math.h with clang using a C standard before C11, and using -pedantic, it will result in warnings similar to: bug254714.c:5:11: warning: '_Generic' is a C11 extension [-Wc11-extensions] return !isfinite(1.0); ^ /usr/include/math.h:111:21: note: expanded from macro 'isfinite' ^ /usr/include/math.h:82:39: note: expanded from macro '__fp_type_select' ^ This is because the block that enables use of _Generic is conditional not only on C11, but also on whether the compiler advertises support for C generic selections via __has_extension(c_generic_selections). To work around the warning without having to pessimize the code, use the __extension__ keyword, which is supported by both clang and gcc. While here, remove the check for __clang__, as _Generic has been supported for a long time by gcc too now.
