Hi...

In gdbtk.c there is a protoype missing for the windows only function 
close_bfds(). This is required due to recently enabled 
-Wmissing-prototype compilation.

Changelog:

2012-03-19  Roland Schwingel <roland.schwingel@onevision.com>

         * generic/gdbtk.c: Add prototype for close_bfds().

Any comments? Is this ok?

Roland
