You said we have to kludge them up as arrays. I did not. I kludged up
the C string as a pointer to a Fortran string, and called strlen to
get the length of the C string. You also said we can only interop with
length-1 character strings. My kludge was valid Fortran and works with
strings of any length up to some sane limit that you can specify.
You cannot expect a C pointer to carry information about the length of
the string. C strings are nul terminated, which is precisely why we
have strlen. When C has to use strlen to get the length of a C string,
so does Fortran. You cannot use the Fortran standard to change the
behaviour of C.

Only if you have an incredibly stupid compiler.
