I had to punt on Apple's port. libiconv-59.tar.gz is libiconv-1.11. It
is too old to be useful.

libiconv-utf8mac is based on libiconv-1.16 and worked fine. It took my
patches after I figured out the complete procedure. On the upside,
libiconv-utf8mac works on Linux and Solaris too. So there is support
for UTF-8-Mac if needed.
