31// NB: MSLU only covers Win32 API, it doesn't provide Unicode implementation of
32// libc functions. Unfortunately, some of MSVCRT wchar_t functions
33// (e.g. _wopen) don't work on Windows 9x, so we have to workaround it
34// by calling the char version. We still want to use wchar_t version on
35// NT/2000/XP, though, because they allow for Unicode file names.
36//
b36de7d0 37// Moreover, there are bugs in unicows.dll, of course. We have to

38// workaround them, too.
