Update.
2000-03-23 Bruno Haible <haible@clisp.cons.org>
* iconv/gconv_int.h (__gconv_transform_ucs2little_internal,
__gconv_transform_internal_ucs2little): Remove declarations.
* iconv/gconv_simple.c (__gconv_transform_ucs2_internal,
__gconv_transform_internal_ucs2): Never need to bswap_16.
(__gconv_transform_ucs2reverse_internal,
__gconv_transform_internal_ucs2reverse): Always need to bswap_16.
