This function is only available in the headers if unconditionally targeting a version >= XP. It is not strictly necessary, since we try loading these functions dynamically at runtime on windows in the fallback, but this makes things a bit faster and more straightforward. On mingw32, this function isn't visible by default, while it is on mingw64 (on both 32 and 64 bit). Signed-off-by: Martin Storsjö <martin@martin.st>
