Make under Windows fails
Hey there!
I just tried to compile the 3.6.5 release commit without success.
After I ran cmake -G "MinGW Makefiles" ., mingw32-make fails at FileUtils.cpp with the following error:
...\OpenSceneGraph\src\osgDB\FileUtils.cpp: In function 'bool osgDB::makeDirectory(const string&)':
...\OpenSceneGraph\src\osgDB\FileUtils.cpp:161:19: error: aggregate 'osgDB::makeDirectory(const string&)::stat64 stbuf' has incomplete type and cannot be defined

This seems to be a relatively old issue, as I found the same error in a Mail thread from 2004 but as I am relatively new to C++, I am not sure how to apply their solution (as it does not seem appropreate having to change the source code, just to use make instead of visual studio) or if even a fix inside some configuration might be possible.
Could you try the OSG-3.6 branch to see if fixes applied to it since 3.6.5 fix the issue.

Mingw-w64 has _stat64 structure and function is called _stat64. Maybe OSG expects POSIX OS when compiling with GCC and is using stat64? On Mingw, best would probably be just using regular stat and defining _FILE_OFFSET_BITS=64, this makes "stat" being define for _stat64. See msys64\mingw64\x86_64-w64-mingw32\include\sys\stat.h.
