I think what you should check for is iconv.h since this missing header
caused compilation problem. Moreover it covers the case of libiconv w/o
libiconv-devel.

You're right it was some leftover in build directory. When I rebuild
from clean untar it worked fine.

So you need to use %lu or %lx on cygwin.

I've tested with previous tarball. I'll retest on both systems with new one.
