It's probably expecting that it can do something put

extern int libiconv_close();

in a source file and then just link it.  That doesn't necessarily work
on Windows.  You may have to mark the declaration with declspec(dllimport);.

The function should be auto-imported automatically but maybe there is
a warning showing up or something which is confusing autoconf.
