+// Implementation for long-path-aware open/mkdir/access/etc. on Windows, as well
+// as for the supporting utility functions.
+//
+// These functions convert the input path to an absolute Windows path
+// with "\\?\" prefix, then pass that to _wopen/_wmkdir/_waccess/etc.
+// (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.

+// Comment this out to fall back to using the ANSI versions (open, mkdir, ...)
+// instead of the Unicode ones (_wopen, _wmkdir, ...). Doing so can be useful to
+// debug failing tests if that's caused by the long path support.
