Why do not you test ?

I'm running 3.16.5, with following code:
    const char *lower;
    const char *equal;
    const char *higher;

    lower = gtk_check_version(3, 16, 4);
    equal = gtk_check_version(3, 16, 5);
    higher = gtk_check_version(3, 16, 6);

    printf("The lower is: %s\n", lower);
    printf("The equal is: %s\n", equal);
    printf("The higher is: %s\n", higher);

the output is following:

The lower is: (null)
The equal is: (null)
The higher is: GTK+ version too old (micro mismatch)

so, as you can see:
(check version) <= running version returns null;
(check version) > running version returns error string;
