+! This file contains all the configure test programs 
+! used by autotools and cmake. This avoids having to
+! duplicate code for both cmake and autotool tests.
+! For autotools, a program below is chosen via a
+! sed command in aclocal_fc.m4. For cmake, a program
+! below is chosen via the macro READ_SOURCE in 
+! HDF5UseFortran.cmake
