Hi Werner, right, my Fortran compiler is usually gfortran or g95 - g77 is a very old compiler that is no longer actively maintained. I can imagine that the compiler does not produce import libraries - shared libraries under Windows simply have too many pecularities, so they are probably beyond g77's capabilities. dlltool is the way forward here.
As to x23f: the trim() function is not a FORTRAN 77 function. It was introduced in Fortran 90. (This does not show up when you use an F90 compiler - sigh) I will look into this one.
