[Bug fortran/32732] [Bind C] Character scalars are passed as arrays

[Tobias Burnus]

Hi,

Thanks Angelo for testing. I'm mostly interested in platforms where ISO
Bind C fails (such as ia64 HP-UX or some(!) powerpc64-unknown-linux-gnu)
and I assume it works on i686 Linux. If it does not I am highly
interested in knowing what fails.

In any case, you found some bugs in my test case; besides the
integer-kind problem the following real programming error:

And another mistake by me; it should be:

  call printf("complex float", sizeof(cmplx(0.0, 0.0, c_float_complex)), c_float_complex);
  call printf("complex double", sizeof(cmplx(0.0, 0.0, c_double_complex)), c_double_complex);
  call printf("complex long double", sizeof(cmplx(0.0, 0.0, c_long_double_complex)), c_long_double_complex);


I was passing c_*_complex not  as KIND but at imaginary number to
"cmplx"; thanks for catching this.
