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.
