> macOS 15.4 added the strchrnul() function in libc. [1]
Here's an improvement for users of the newest macOS SDK (that
includes the header files of macOS 15.4) on older macOS versions

2025-05-27 Bruno Haible <br...@clisp.org>
strchrnul: Fix for users of the current macOS SDK.
Reported in <https://savannah.gnu.org/bugs/?67141>.
* m4/strchrnul.m4 (gl_FUNC_STRCHRNUL): Use gl_CHECK_FUNCS_ANDROID_MACOS
instead of gl_CHECK_FUNCS_ANDROID.
