Otherwise, set current status to the unit status. * io/unit.c (get_internel_unit, init_unit): Remember to set flags_delim initially to DELIM_UNSPECIFIED so defaults come out correctly. * io/write.c (write_character): Add a new function argument "mode" to signify that raw output is to be used vs output with delimiters. If the mode is set to DELIM (1) proceed with delimiters. (list_formatted_write_scalar): Write the separator only if a delimiter was previously specified. Update the call to write_character with the mode argument given. (namelist_write_newline): Use the mode argument. (nml_write_obj): Use the mode argument. Remove use of tmp_delim. Write the semi-colon or comma correctly only when needed with using delimiters. Cleanup whitespace. (namelist_write): If delim is not specified in namelist I/O, default to using quotes. Get rid of the tmp_delim variable and use the new mode argument in write_character. 2014-02-21 Tobias Burnus PR fortran/60286 * libgfortran/io/inquire.c (yes, no): New static const char vars. (inquire_via_unit): Use them. Use OPEN mode instead of using POSIX's access to query about write=, read= and readwrite=. 2014-01-20 Jerry DeLisle Dominique d'Humieres * io/write_float.def (output_float): Remove inadvertent test code from previous patch. 2014-01-19 Jerry DeLisle Dominique d'Humieres PR libfortran/59771 PR libfortran/59774 PR libfortran/59836 * io/write_float.def (output_float): Fix wrong handling of the Fw.0 format. (output_float_FMT_G_): Fixes rounding issues with -m32. 2014-01-11 Jerry DeLisle Dominique d'Humieres Steven G. Kargl PR libfortran/59700 PR libfortran/59764 * io/io.h (struct st_parameter_dt): Assign expanded_read flag to unused bit. Define new variable line_buffer_pos. * io/list_read.c (free_saved, next_char, l_push_char, read_logical, read_real): Replace use of item_count with line_buffer_pos for line_buffer look ahead. (read_logical, read_integer, parse_real, read_real, check_type): Adjust location of free_line to after generating error messages to retain the correct item count for the message. 2014-01-02 Richard Sandiford Update copyright years Copyright (C) 2014 Free Software Foundation, Inc.
