EDIT: I take that back - apparently it is possible to do this in your case

RewriteRule ^(.+)/$ index.php?m=$1 [QSA]

Apache cannot use $_GET parameters to build the new URL ; you'll have to change the structure of the URL.

From Apache's documentation:

By default, the query string is passed through unchanged. You can, however, create URLs in the substitution string containing a query string part. Simply use a question mark inside the substitution string to indicate that the following text should be re-injected into the query string. When you want to erase an existing query string, end the substitution string with just a question mark. To combine new and old query strings, use the [QSA] flag.

Using the [QSA] flag you can rebiuld your URL as you have, and the existing query string parameters will be appended, or passed through.

Hope this helps.
