>Description:
Previous versions automatically found and linked libiconv, but current version does not.
Please support libiconv.

It's very important for Japanese.
Because character encodings for Japanese used in UNIX world (EUC-JP or
UTF-8) and DOS/Windows world (Shift_JIS) are different.
And to make matters worse, we cannot use Shift_JIS with mingw tools, because uses '\' (0x5c) as the second byte of some characters so that many no-localized tools including gcc are confused.
In short, libiconv support is essential.
