Oh - I missed one.  gdb_has_a_terminal() now works, so query() prints
questions instead of assuming yes.  That makes a big usability
difference.

Unfortunately, this is true for Windows consoles, but not for a
Windows-native GDB run from a Cygwin SSH terminal - there stdin
is just a pipe.  I checked with Chris, and there really doesn't seem to
be a useful way around this.  So if you want to use a native Windows
GDB, use it in a native Windows console (or via a pipe explicitly -
e.g. Eclipse).
