[Bug c++/23738] New: error with documentation or error with -M used in conjunction with -w

Hi.
I wanted to disable all warnings in dependency file generation (-M or -MM) but
it is not working.
I tried -MM and although the documentation says:
       -M  Instead of outputting the result of preprocessing, output a rule
suitable for........
           Passing -M to the driver implies -E, and suppresses warnings with an
implicit -w.
, it is not working.
-M or -MM plus -w does not work either.
