VS 2012.  The first file with error is this.
src\sys\objects\mpinit.c(261) : error C2065: 'MPI_UNSIGNED_LONG_LONG' : undeclared identifier
src\sys\objects\mpinit.c(279) : error C2065: 'MPI_UNSIGNED_LONG_LONG' : undeclared identifier
src\sys\objects\mpinit.c(287) : error C2065: 'MPI_UNSIGNED_LONG_LONG' : undeclared identifier
src\sys\objects\mpinit.c(329) : error C2065: 'MPI_UNSIGNED_LONG_LONG' : undeclared identifier
src\sys\objects\mpinit.c(408) : error C2065: 'MPI_UNSIGNED_LONG_LONG' : undeclared identifier
src\sys\objects\mpinit.c(449) : error C2065: 'MPI_UNSIGNED_LONG_LONG' : undeclared identifier

Essentially, all files that use MPIU_SIZE_T see it as
MPI_UNSIGNED_LONG_LONG and give this error.
