They are used by makefile dependency tracking rules, which is under 
Automake's domain (the depcomp script, as well as automake rules run at 
configure time to determine which style of compiler dependency to 
request of the depcomp script).

Actually, you'll probably have better luck on the automake list, since 
autoconf itself does not touch any -M option.
