M-q works fine for me with C as well as C++ style comments, both ways, 
i.e. shorting long comments and extending short comments to fill the line.

The only "quirk" I found:

Using C-style comments, if the original comment looks like this:

/* This is a short comment
   which is extended                      */

the resulting comment is:

/* This is a short comment which is extended  */

Notice the two spaces after the last word 'extended', before the close 
comment marker.

I would have expected either:

/* This is a short comment which is extended                      */

i.e. the whitespace of the original comment is preserved, or

/* This is a short comment which is extended */

i.e. the whitespace is zapped except one space before the close comment 
marker.

This might be nitpicking but I thought I bring it up.

Christoph
