	LIBERROR_* macros instead of IOERROR_ macros.
	* trans-intrinsic.c (gfc_conv_intrinsic_function): Use
	LIBERROR_END and LIBERROR_EOR instead of hardcoded constants.

	CONVERT_NATIVE.
	(gfc_handle_option): Use GFC_CONVERT_* macros instead of CONVERT_*.

	* libgfortran.h: Include gcc/fortran/libgfortran.h.
	Remove M_PI, GFC_MAX_DIMENSIONS, GFC_DTYPE_*, GFC_NUM_RANK_BITS,
	error_codes, GFC_STD_*, GFC_FPE_* and unit_convert.
	* runtime/environ.c (variable_table): Use GFC_*_UNIT_NUMBER instead
	of hardcoded constants.

	LIBERROR_* macros instead of ERROR_*.
	* io/file_pos.c (formatted_backspace, unformatted_backspace,
	st_backspace, st_rewind, st_flush): Rename macros.
	* io/open.c (convert_opt, edit_modes, new_unit, already_open,
	st_open): Likewise.
