Optional parameters in smpp pdu's?

Hello.

As I see, kannel-1.1.5 doesn't implement optional parameters parsing
in smpp pdu's, and my operator sends me sms'es with the body in the
payload (thus setting sm_length to 0 and kannel thinks it's got an empty
message).
Are there any patches out there for this? (Maybe there are, and I won't
reinvent the well :)
