In what sense do the files not work, exactly?

For example, does your zic's output match the output generated by zic
on GNU/Linux or Unix machines?  If so, then the problem is not with
the way you built zic; it lies somewhere else.  If not, then exactly
how does the output differ?

zic should be quite reliable on GNU/Linux and Unix platforms, as its
output is used in a lot of places.  Occasionally we get bug reports,
and we do fix any specific bugs that are reported.  It is certainly
quite possible that there is a portability bug when zic is run on
non-POSIXish platforms.  However, your report did not contain enough
details for us to know what the bug is, or how to reproduce it.
