+Subject: [PATCH] build: Fix strndup detection on MinGW
+
+GCC and meson conspire together to incorrectly detect that strndup()
+exists on MinGW as __builtin_strndup, when no such function exists. As a
+work around, meson will skip looking for __builtin functions if an
+'#include' is in the prefix, so add '#include <string.h>' when looking
+for strndup().
+
+See: https://github.com/mesonbuild/meson/issues/3672
