[Samba] PDC migration: printing trouble. Summary.

UPDATE:  I've realized that this seems to be an issue with the compiler flags used to build samba.
I've realized that i need to define _LARGEFILE_SOURCE, _LARGEFILE64_SOURCE, and _FILE_OFFSET_BITS=64.

I've done this, but still have no luck reading files larger than 4GB.  Anyone have suggestions?

Thanks,
Matt
