After looking through gdb-mi.el more carefully, I see that emacs doesn't 
really need to know the GDB version.  So I withdraw my complaint.  But I 
think the variable gdb-version should probably be renamed to reflect its 
real purpose, perhaps to gdb-supports-non-stop.

This still seems wrong, unless there's some reason that pretty-printing 
is only useful in non-stop mode.

The attached patch implements my suggestions (and also makes a couple of 
whitespace changes).

OK to apply?
