Thanks.  GDB 7.0 is the newest version that will run, but it complains
that the executable is built with DWARF-4 debug information, while it
only supports DWARF-2.  I verified that CFLAGS does contain -gdwarf-2,
which I believe configure defaults to on MinGW.

Do you know what might be wrong here? TIA.
