I don't believe you can make this work.  I spent some time last year
looking at it with my Slackware 3.6 (also libc5), and installed libiconv
and libutf8 - but found that the system headers declared some things
such as wchar_t incompatibly.  (wcwidth would be provided by libutf8,
but the conflicting definition of wchar_t meant that what I built wouldn't
work consistently).
