The pdwtags program changed its whitespace formatting for enum
values in release 1.19:

enum admin_procedure {
- ADMIN_PROC_CONNECT_OPEN = 1,
- ADMIN_PROC_CONNECT_CLOSE = 2,
- ADMIN_PROC_CONNECT_GET_LIB_VERSION = 3,
- ADMIN_PROC_CONNECT_LIST_SERVERS = 4,
- ADMIN_PROC_CONNECT_LOOKUP_SERVER = 5,

+ ADMIN_PROC_CONNECT_CLOSE = 2,
+ ADMIN_PROC_CONNECT_GET_LIB_VERSION = 3,
+ ADMIN_PROC_CONNECT_LIST_SERVERS = 4,
+ ADMIN_PROC_CONNECT_LOOKUP_SERVER = 5,
Workaround this by telling diff to ignore whitespace changes.
