    It is.

    Yes, that's unfortunate, because latest versions of GCC (3.x and
    later) produce binaries that are very hard to debug in the optimized
    build.

    Not true.  You need to start GDB in the src/ directory.  Then you can
    say "run /path/to/emacs/emacs.exe".

    You can have the shortcut run a batch file that would invoke GDB and
    run Emacs inside it.  You can have a .gdbinit file that does some of
    that.  And there are many other options.

Thanks for your time, Eli; I'll work on it today.
