extensibility check

parent 7ccf2a44
0.8.14: 2004-Jun-30
* Fixed compiler: extensibility of CHOICE and SET type has not been
taken into account during table construction.
(Test case 47) (Severity: high, Security impact: low)
0.8.13: 2004-Jun-29
* Fixed compiler: the skip values for IMPLICIT tagging were broken
