cipxtxck.c:search_and_get_matching_connection_state 
replace do {...} while; by while {...}; - code generation problem

cipxrxun.c: uncompress_header
check for TYPE_NORMAL_IPX before masking with PACKET_TYPE_MASK

cipxinit.c: added cipx_reset_connection_states() to flush all the
connection_state structures. Called from PPP when the link goes down.

Naveen.P.N. 22/04/1997
enum COMMUNICATION_MODE, PACKET_DIRECTION and HEADER_AGE are included
under conditional compliation to avoid clash between same enums in the 
VJC module.
