    Fortran: Fix directory stat check for '.' [PR103560]

    MinGW does not like a call to 'stat' for './' via gfc_do_check_include_dir.
    Solution: Only append '/' when concatenating the path with the filename.

            save include path.
            (open_included_file): Use '/' in concatenating path + file name.
            * module.cc (gzopen_included_file_1): Likewise.
