Fix for Bug#34274: Invalid handling of 'DEFAULT 0'

Browse Source 
for YEAR data type.

The problem was that for some unknown reason 0 was not allowed
as a default value for YEAR data type. That was coded before BK.
However the Manual does not say a word about such a limitation.
Also, it looks inconsistent with other data types.

The fix is to allow 0 as a default value.
