This seems awfully overcomplicated, due to the usual problem that
nobody bothers to read the section of the man page that starts at
MULTIPLE INPUT BUFFERS.

C version:

  while(1) {
    YY_BUFFER_STATE *bp;     
    char *f = readline(">>> ");

    bp = yy_scan_string(f);
    free(f);
    yy_switch_to_buffer(bp);

    yyparse();	/* eat the input */

    yy_delete_buffer(bp);
  }
     
R's,
