For the following code:
#define MYMACRO(NAME) myOutputStream << #NAME;
MYMACRO(Group)
you would expect that "Group" would be output. However, as there are many overloaded operator<< functions, none of which take a const char* argument, the function that's actually called is operator<<(bool). Hence what actually gets output is "TRUE".
An actual example of this is in serializers\osgAnimation\Animation.cpp, WRITE_CHANNEL_FUNC2.
So the simple solution to this is to add operator<<(const char*), attached.
