re PR libfortran/35863 ([F2003] Implement ENCODING="UTF-8")

2008-06-13  Jerry DeLisle  <jvdelisle@gcc.gnu.org>

	PR fortran/35863
	* libgfortran.h: Change l8_to_l4_offset to big_endian and add endian_off.
	* runtime/main.c: Fix error in comment. Change l8_to_l4_offset to
	big_endian. (determine_endianness): Add endian_off and set its value
	according to big_endian.
	* gfortran.map: Add symbol for new _gfortran_transfer_character_wide.
	* io/io.h: Add prototype declarations for new functions.
	* io/list_read.c (list_formatted_read_scalar): Modify to handle kind=4.
	(list_formatted_read): Calculate stride based on kind for character type
	and use it when calling list_formatted_read_scalar.
	* io/inquire.c (inquire_via_unit): Change l8_to_l4_offset to big_endian.
	* io/open.c (st_open): Change l8_to_l4_offset to big_endian.
	* io/read.c (read_a_char4): New function to handle formatted read.
	* io/write.c: Define GFC_CHAR4(x) to improve readability of code.
	(write_a_char4): New function to handle formatted write.
	(write_character): Modify to accept the kind parameter and adjust for
	endianess of the machine. (list_formatted_write): Calculate the stride
	resulting from the kind and adjust the list_formatted_write_scalar call
	accordingly. (nml_write_obj): Adjust calls to write_character.
	(namelist_write): Likewise.
	* io/transfer.c (formatted_transfer_scaler): Rename 'len' argument to
	'kind' argument to better describe what it is. Add calls to new
	functions for kind == 4. (formatted_transfer): Modify to handle the case
	of type character and kind equals 4 to pass in the kind to the transfer
	routines. (transfer_character_wide): Add this new function.
	(transfer_array): Don't set kind to the character string length. Adjust
	strides bases on character kind.
	(unformatted_read): Adjust size based on kind for character types.
	(unformatted_write): Likewise. (data_transfer_init): Change
	l8_to_l4_offset to big_endian.
