Update.
1998-04-14 18:22 Ulrich Drepper <drepper@cygnus.com> * iconv/gconv_builtin.c (__gconv_get_builtin_trans): Initialize counter element of step. * iconv/gconv_dl.c: Don't mark get_sym as internal function. * iconv/gconv_simple.c (__gconv_transform_ucs4_ascii): Correct loop termination test. (__gconv_transform_ucs4_utf8): Likewise. Remove unnecessary variable ACTUALLY. (__gconv_transform_utf8_ucs4): Correct test for empty input.
