Update.
2001-09-01 Ulrich Drepper <drepper@redhat.com> * iconv/gconv_cache.c: Rename variable cache to __gconv_cache and export it. * iconv/Versions (libc) [GLIBC_2.2.5]: Export __gconv_cache. * iconv/iconv_prog.c (insert_cache): New function. (print_known_names): If cache is used call insert_cache to use the information from the cache [PR libc/2509].
