	* iconvdata/iso-2022-cn-ext.c: Likewise.
	* iconvdata/ansi_x3.110.c: Add cast to avoid warning.
	* iconvdata/big5.c: Likewise.
	* iconvdata/big5hkscs.c: Likewise.
	* iconvdata/iso_6937.c: Likewise.
	* iconvdata/iso_6937-2.c: Likewise.
	* iconvdata/t.61.c: Likewise.
	* iconvdata/iso646.c: Add prototypes for gconv_init and gconv_env.
	* iconvdata/unicode.c: Likewise.
	* iconvdata/utf-16.c: Likewise.
	* iconvdata/cns11643.h (ucs4_to_cns11643): Define needed as size_t.
	* iconv/gconv_trans.c (__gconv_translit_find): Avoid one warning
	with little code shuffling.
