I found this in the CHANGE_LOG file for version 6.7.0:

            Added the typedef "prod_class_t" to the header-file "ldm.h"
            and changed all code and documentation to use it instead of
            the typedef "prod_class".  This was done to allow "ldm.h" to
            be processed by a C++ compiler.  The typedef "prod_class"
            still exists for backward compatibility -- though it is no
            longer used in the code.  Both C and C++ programmers should
            now use "prod_class_t" instead of "prod_class".

I recommend getting the latest version of the LDM and changing all your uses of 
"prod_class" to "prod_class_t".
