In fact in c const "char *arg" does not mean a constant pointer to a 
character, but a pointer to a constant character,

As in C you need to pass explicit pointers and in Pascal you can do this 
implicitly by using var or const, I suppose

function some_fuc(const arg: char): cint; cdecl; external;

should do this.
