Two fixed files:
osgPlugins/osgjs/JSON_Objects
osgPlugins/stl/ReaderWriterSTL.cpp.
They did not compile with VS 2008 (recent master from Github). It looks like they defined stdint types (missing in VS 2008) but code using them also included <osg/Types> header. Errors were caused by minor differences in signed int definitions. I just removed own definitions and added include<osg/Types> instead. It solves the problem and makes the code clearer now.
