[GEMPAK #LLA-719485]: Broken decoders, dcwarn and similar

Hi Mike,

I don't have a lot to go off of here, and at Unidata we have not encountered 
this problem.   dcwarn, dcwtch and the lot are decoding correctly.  One thing 
of interest is that you're running GEMPAK decoders version 6.8.0.  

The dcwarn source has not changed since 6.7.0, but for 7.0 I updated the 
Makefile with the addition of $(XMLLIB) $(ZLIB) to LIBINC:

https://github.com/Unidata/gempak/tree/master/gempak/source/programs/dc/dcwarn

I'm sorry I can't provide a fix.  I would like to see if the errors persist if 
you rebuild from 7.1.0 source, or install the 7.1.0 RPM.
