The official MPI specification (May 94) only specifies a MPI_GET_COUNT,
which is in fact implemented in MPICH (file src/pt2pt/getcount.c in the
MPICH-1.05 distribution).

The standard explains how to extract the SOURCE and TAG fields from
the "status" parameter (pp. 20-21):

 C:       use "status.MPI_SOURCE" or "status.MPI_TAG"
 FORTRAN: use "status(MPI_SOURCE)" or "status(MPI_TAG)"
