Tested it:

    void GLSupport::initialiseExtensions(void)
    {
        // Set version string
        const GLubyte* pcVer = glGetString(GL_VERSION);
fprintf(stderr,"100\n");

        assert(pcVer && "Problems getting GL version string using glGetString");
fprintf(stderr,"101\n");
        String tmpStr = (const char*)pcVer;
fprintf(stderr,"102\n");
        LogManager::getSingleton().logMessage("GL_VERSION = " + tmpStr);
fprintf(stderr,"103\n");
        mVersion = tmpStr.substr(0, tmpStr.find(" "));
fprintf(stderr,"104\n");

It looks like it is threaded but I'm not sure.

How can I output whatever glGetString returns?
