wine3277..

I sent Daniel this small test app:

void main(void) {
    Display *display;
    char    *displayname = NULL;
    int nCfgs = 0;
    GLXFBConfig* cfgs = NULL;
    int att_list[64];
    int att_pos = 0;

    display = XOpenDisplay (displayname);
    printf("%s %s \n",glXGetClientString(display,GLX_VENDOR), displayname);

    ADD2(GLX_RENDER_TYPE, GLX_RGBA_BIT);
    ADD2(GLX_BUFFER_SIZE, 0);
    att_list[att_pos] = None;
    cfgs = glXChooseFBConfig(display, DefaultScreen(display), att_list, &nCfgs);

    if (cfgs == NULL) {
        printf("cfgs is null\n");
    } else {
        printf("Found configs\n");
    }

and it returns cfgs is null which I wouldn't have expected, but it looks like there's a basic
problem with glXChooseFBConfig
