I don't know where you found the documentation for this options, but
it's supposed to say (from the font used, like on the online HTML
docs: http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gfortran/Directory-Options.html)
that it's a -M options that takes a directory argument joined to it:

gfortran -Mmy_directory will write the module files into the directory
named my_directory.
