* module/rnrs/io/ports.scm: (file-options, buffer-mode, eol-style) (error-handling-mode, make-transcoder, native-transcoder) (latin-1-codec, utf-8-codec, utf-16-codec) (call-with-bytevector-output-port, open-file-input-port) (open-file-output-port, make-custom-textual-output-port) (flush-output-port, put-char, put-datum, put-string, get-char) (get-datum, get-line, get-string-all, lookahead-char) (standard-input-port, standard-output-port, standard-error-port): Define all of these. (call-with-port): Don't use `dynamic-wind', as it is against its specification in R6RS 8.2.6. * module/rnrs.scm: Export procedures added. * module/rnrs/io/simple.scm (call-with-input-file) (call-with-output-file): Define these in terms of R6RS procedures to get correct exception behavior.
