Such iconv binaries are completely broken.

Sure: -DUNICODE changes many prototypes in the <windows.h> headers,
to use wchar_t* strings instead of char* strings. It is absolutely normal
that you get garbage when trying a Unix program with this flag.

Request denied. Please learn what -DUNICODE means and why it was terribly silly
by Microsoft to introduce this option.

The libtool mailing lists are the right place to post such patches,
since the original source is in libtool.m4.
