	(_IO_file_open): If _IO_FLAGS2_NOTCANCEL is set, use open_not_cancel.
	(_IO_new_file_open): Recognize 'c' flag in mode string.
	(_IO_file_read): If _IO_FLAGS2_NOTCANCEL is set use read_not_cancel.
	(_IO_new_file_write): If _IO_FLAGS2_NOTCANCEL is set use
	write_not_cancel.
	* iconv/gconv_conf.c: Use fopen with 'c' mode flag.
