It's a bit brutal but you can simply do this:

   gmsh file.med -3

(Gmsh will not remesh anything since the CAD representation is purely 
"discrete".)

A cleaner way would be to write a little script containing

   Save "file.msh";
   Exit;

and parse it with "gmsh file.med myscript -": this will save the file in 
.msh format with the default options and exit. You could also add 
various options to control the format before the Save command in the 
same script.
