Nobody has reported this problem before. Therefore it is likely 
that nobody has tried to compile the code with the PGI compiler 
recently.

The DAT headers define UINT64_C on line 147 of 
dat/dat_platform_specific.h

The definition there is guarded by an ifndef

You must be including stdint.h sometime after you include udat.h

If you include stdint.h before you include udat.h, the problem should 
go away.

Did you try changing u_int64_t to uint64_t?
