-// Implementation for long-path-aware open/mkdir/access on Windows.
-//
-// These functions convert the input path to an absolute Windows path
-// with UNC prefix if necessary, then pass that to
-// _wopen/_wmkdir/_waccess (declared in <io.h>) respectively. This
-// allows working with files/directories whose paths are longer than
-// MAX_PATH (260 chars).
-//
-// This file is only used on Windows, it's empty on other platforms.
