See the following threads:
[RFC/RFA] avoid spurious Watchpoint X output on cygwin native target.
http://sources.redhat.com/ml/gdb-patches/2002-07/msg00323.html

and
RFA: Make cli-out follow gdb_stdout
http://sources.redhat.com/ml/gdb-patches/2002-07/msg00366.html
as well as
(which is a different thread, probably because I didn't use Relpy...)
http://sources.redhat.com/ml/gdb-patches/2002-08/msg00549.html

But honestly, I don't know if the this new function solves the
problem...
IMHO, standard gdb sources should not have to worry at all about
the possible fact that an interpreter is present...
The fact that standard gdb code redirects gdb_stdout (or gdb_stderr)
should be respected by any interpreter, no?
Thus I still think that the best solution is the double pointer one...
but Andrew is stronly opposed to that solution....
