With this patch the distinction between a 'long' KLONG and a 'long long' KLONG is being abandoned in favor of a consistent declaration as 'long' only. Plus we would have also defined it as 'unsigned' except there exists much code already explicitly specifying the qualifier. Signed-off-by: Jim Warner <james.warner@comcast.net>
