Gdb is not in my path anymore, so cmd.exe does not recognize that.
But I have an old version.

If you want me to use GDB I'm afraid you will need to give me
simple, clear instructions, step-by-step, including the download.

If it's simple and I don't spend hours picking it up, a dividend
might be that I could use it with other Emacs crashes - assuming
the instructions apply there also.
