I didn't find an example where checking the natural format would not work.
But that may not mean much :-)
Boolean could have been a problem (0x1, 0x2, 0x3 etc are all "true" in natural),
but it seems that for now, GDB always shows 0x1 for true.

A safer way may be to have GDB check for content difference, as it used to do
before and to also check the natural printed format for the case of char*
(to detect a change from "GDB" to "GNU").
