In CMakeTestFortranCompiler we build a test program using a Fortran 90 construct to check whether the compiler supports the language. Some compilers have options to require explicit variable types. Fix the test program to use an explicit variable type so it passes under such a configuration. Suggested-by: Neil Carlson <neil.n.carlson@gmail.com>
