Thanks for adding this entry.  This is probably a nit, but Emacs default
is '-gdwarf-2'.  Maybe the entry should stick to that and shouldn't open
up a new possible source of confusion?

I know.

If you think this could cause confusion.  I thought it won't, and
"-gdwarf-4" gives you a better debug info.  (We don't use that by
default because I don't know which version of MinGW GCC started
supporting it.)

Ah, that was intentional, so let's keep it that way.
