Don't invoke GDB from inside Emacs, that's only good when you do that
from the same version of Emacs you are debugging, and even then there
are a few gotchas.

Instead, go to the directory where you have .gdbinit, and type from
the shell prompt:

 >gdb /path/to/emacs.exe RET

When GDB ends its initialization and shows the "(gdb)" prompt, type:

 (gdb) run --debug-init

You should now have your normal Emacs session, with all the
customizations you normally have.
