Compiling the attachment gives the error message

Attached is a 9 line file which gives the following diagnostic

EnumKind.f90:7.19:

    integer(k) :: C
                   1
Warning: Component 'c' in derived type 't' at (1) may not be C interoperable,
even though derived type 't' is BIND(C)

The NAG and Intel compilers (I have been told) don't give any such warning.
