bug#12113: 24.0.96; Incorrect echoing of gdb output

[William M. (Mike) Miller]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

When I run M-x gdb and debug a program, some gdb output that should
appear is suppressed, and some gdb output that should be suppressed is
echoed.  The version of gdb I am using is

    GNU gdb (GDB) 7.3.50.20111026-cvs (cygwin-special)

and I am using gdb-many-windows mode.

In particular, if I type "next" in the gud interaction buffer, the
source line of the execution point is echoed in the buffer, just as it
would be if I were using gdb in an xterm outside of emacs.  It is
correctly suppressed if I use the graphical "next" button at the top of
the window.

Conversely, if I use the graphical buttons for "run", "continue", or
"step", the gdb output showing the function name and parameter values is
not echoed in the gud interaction buffer; it does appear if I type those
commands instead of using the graphical buttons.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.0.96/etc/DEBUG.
