mpiuni/mpi.h also has this unguarded statement. Do all Windows compilers now provide 'long long'? #define MPI_LONG_LONG_INT sizeof(long long) We could make mpiuni define MPIU_SIZE_T itself instead of jumping through hoops to find the matching type. Chetan, what's your perspective about using stdint.h?
