I'll submit this to osg-submissions to make sure it gets fixed. The reason for this issue is that when one compiles with MinGW (as opposed to MSVC) one needs to #define _WIN32_WINNT properly. The MinGW header files enforce the _WIN32_WINNT preprocessor definition for anything added to the Windows API after Windows 95. The Microsoft Platform SDK (at least the Windows 2003 Server release), on the other hand, does not appear to require you to #define anything to use OS functions introduced with Windows 2000. Using GetLongPathName() requires Windows 2000 or greater on the target platform running OSG. A cursory examination of the OSG code base reveals no additional dependency on Windows 2000 that I can see, so I just wanted to bring this to everyone's attention in case it's cause for concern. -- Philip Lowman
