Thanks.  I've pulled that into my readline upgrade series.

I have to disable guile to get this test to work.  When guile is
enabled, there's an early SEGV in the garbage collector -- it is
expected and is caught by the GC, but this test case doesn't know how to
cope.

I'm looking now at importing readline 8.0.

I still don't really know what to do about the readline-related hack in
the mingw gdb_select.  I'd like to remove it, but I can't test it and I
don't know whether it's still needed.
