Hi all, i ran into the same problem (when compiling in vs2012), see this changeset: https://github.com/openscenegraph/OpenSceneGraph/commit/e64e70870d51873621be4f90f1301640d882704d
char* start_of_string; this is caused by the fact that the file is c code, not c++ and the new variable needs to be declared at the start of the block.
