Revision 1.4 2000-08-16 13:06:07 florian
+ support of 64 bit integer constants
Revision 1.3 2000/08/13 12:54:56 peter
* class member decl wrong then no other error after it
* -vb has now also line numbering
* -vb is also used for interface/implementation different decls and
doesn't list the current function (merged)
Revision 1.2 2000/07/13 11:32:50 michael
+ removed logs
