        Implement backtrace output for fatal errors on MS-Windows.
        * w32fns.c (CaptureStackBackTrace_proc): New typedef.
        (BACKTRACE_LIMIT_MAX): New macro.
        (w32_backtrace): New function.
        (emacs_abort): Use w32_backtrace when the user chooses not to
        attach a debugger.  Update the text of the abort dialog.

Currently you cannot control where it is written.

As for how to use it, if you have MinGW installed you can use addr2line:

addr2line -e /path/to/emacs.exe < emacs_backtrace.txt
