4Subject: [PATCH] build: Fix strndup detection on MinGW
5
6GCC and meson conspire together to incorrectly detect that strndup()
7exists on MinGW as __builtin_strndup, when no such function exists. As a
8work around, meson will skip looking for __builtin functions if an
9'#include' is in the prefix, so add '#include <string.h>' when looking
10for strndup().
