Re: [Bayonne-devel] Labels broken on new ccscript ??

[David Sugar]

There were originally several different ways to do labels in ccscript; 
either in the ::xx or xx: form, explicitly as private and/or public xx 
targets, as well as "function" xx.  In ccscript3, the older forms were 
dropped.  Hence we retained private/public xx for direct labels for goto 
and/or gosub, and function xx exclusively as a target of call.
