In the mapping message there is nothing prohibiting multiple FECs to be sent
in the same message.  I do not think you can send multple FEC,Label pairs.
In other words a mapping message can contain 1 (and only one) label TLV but
can contain many FEC elements (with in one FEC TLV).

I have never testes this functionality, but I believe I attempt to handle this
case.

Take a look at ldp_state_func.c:ldp_state_proces() you'll see I attempt to
cycle through all of the FEC elements in the FEC TLV.  Like I said I have
never tested this, so I'm pretty sure it's not going to work, but it is
atleast on the right track :-)
