(svn r7279) -Codechange: [win32] Add Windows95/98 support by using MSLU. Only workaround is that the
wide version of EnumDisplaySettings crashes on win95 no matter what, so use ANSI version.
NOTE: MSLU support is only added to VS2003 project file because VS2005 compiles won't
even run on Windows95.
