Hello George, you're right, while g77 accepts the I-format, gfortran coming with gcc-4.0.2 does not anymore....
Thinking about it, it really seems to be the only viable solution (though I don't know Fortran that much), to have a separate print-function in C.... Setting a tmp-integer-variable to the logical would fail e.g. on pgi-compiler (although he swollowed the I5-formatting)...
