 -fprofile-arcs is broken because the gcj frontend doesn't initialize
 long_integer_type_node.
 
 I've been using the following workaround, but haven't submitted since I'm
 not sure it's the right thing to do.  (I.e. is int_type_node or
 long_type_node the correct size for it?  These are java types, not C
 types.)
