Subject: gnulib: isnan: Fix compilation error in C++ mode Date: Dienstag, 27. Februar 2024, 23:08:47 CET From: Christian Weisgerber <na...@mips.inka.de> To: Bruno Haible <br...@clisp.org> Hi, regarding isnan: Fix compilation error in C++ mode on macOS 14.4 / Xcode 15.2 https://lists.gnu.org/archive/html/bug-gnulib/2024-02/msg00121.html I just came across the same problem on OpenBSD 7.5-beta (clang 16.0.6). I guess the defined() check needs to be extended unless a more generic solution can be found.
