There is not emacs.exe in my source tree after I build Emacs.  There
is only one in the target installation directory
(c:/Programme/Emacs/bin in my case) after `make install' was run
(which is actually a bit annoying).

It's `M-x gdb' to be precise.  Sorry for not writing that beforehand.

Yes.  But maybe I am using the interface in an invalid way.  What I've
done is

* starting Emacs with `emacs -Q'
* changing directory with `C-x C-f c:/Programme/Emacs/bin'
* starting GDB with `M-x gdb RET' and using `emacs.exe' as the
  executable to debug
* loading .gdbinit from GDB with `source /path/to/.gdbinit'
* setting a breakpoint with `b w32_createwindow'
* running Emacs with `run -g 80x30+10+20'

I don't get a backtrace if I start GDB in the source tree where
.gdbinit resides and then use the `emacs.exe' executable from the
installation directory for GDB.  But the `xtype' and `pr' commands
don't seem to work either:

(gdb) p Fassq (Qtop, f->param_alist)
$1 = 23713793
(gdb) pr
(gdb) xtype
(gdb)
