These warnings are probably harmless.

Yes. Nelson, can you please give a little more infor about the locale and the
character that caused this problem? To do this, run these debugging sessions;
what I need is the line number and the local variables values in main():

  env LC_ALL=fr_FR.UTF-8 gdb test-wcrtomb
  run 2

  env LC_ALL=ja_JP.EUC gdb test-wcrtomb
  run 3

  env LC_ALL=zh_CN.GB18030 gdb test-wcrtomb
  run 4

Btw, the bug is probably fixed in FreeBSD 5.1.
