NAME +! H5test_kind +! +! FUNCTION +! This stand alone program is used at build time to generate the program +! H5fortran_detect.f90.

NOTES +! This program is depreciated in favor of H5test_kind_SIZEOF.f90 and is only +! used when the Fortran intrinsic function SIZEOF is not available. It generates +! code that does not make use of SIZEOF in H5fortran_detect.f90 which is less +! portable in comparison to using SIZEOF. +! +! The availability of SIZEOF is checked at configure time and the TRUE/FALSE +! condition is set in the configure variable "FORTRAN_HAVE_SIZEOF". +! +!
