Recent NVHPC compilers now support the REAL16 intrinsic from the ISO_FORTRAN_ENV module. Though they do support real(REAL16), they do not support complex(REAL16), causing a compilation error in the MPI_Sizeof() Fortran subroutine. This patch does test complex(REAL16) on top of real(REAL16), and issue a warning and disable ISO_FORTRAN_ENV:REAL16 support if the former is not supported but the latter is. Thanks Jorge Cabrera for reporting this. Refs open-mpi#13190 Signed-off-by: Gilles Gouaillardet <gilles@rist.or.jp> (cherry picked from commit 58960cc)
