I confused with other Fortran compilers about "fatal error". G77 does not output such a message for apprently invalid sources.

Now, what I want to know is that such a treatment for argument type mismatch is intended by g77 developers or not.

I remember that VAX or CRAY fortran (?) can do run-time argument type check by putting information of argument data type on stack.      

Anyway, compiling in fsplit'ted form is safer (to deceive the compiler :-))...
