2001-09-04 Jakub Jelinek <jakub@redhat.com> * iconv/strtab.c (strtabinit): Initialize null Strent. (newstring): Move len == 0 handling... (strtabadd): ...here. If len == 1, return null Strent. When inserting a suffix of an existing string, check if it is not equal to some suffix already recorded. Copy left and right members over if adding longer string. 2001-09-04 Jakub Jelinek <jakub@redhat.com> * sunrpc/rpc_cout.c (upcase): Account for trailing '\0'. * sysdeps/unix/sysv/linux/alpha/gethostname.c: Include <errno.h>. (__syscall_gethostname): Add prototype.
