Ranjit,

This patch looks good to me (see comments below), but Andrew or Per will 
have to approve it. Did you run it against the jacks testsuite? 
Hopefully it should fix some failures there.

Could you file a separate PR for this case (if one doesn't exist already)?

It would be good to add a comment explaining this to java_acc_ctrl_str. 
Also it might be nice to have a less cryptic method name here - the 
front end is not afraid of long function names ;-) perhaps 
member_accessibility_string ?
