POSIX says:

size_t iconv(iconv_t cd, char **restrict inbuf,
       size_t *restrict inbytesleft, char **restrict outbuf,
       size_t *restrict outbytesleft);

For GNU iconv, whether you have a const in the prototype or not is
configurable.  I think by default it tries to match the prototype
of an existing iconv on the machine.  The FreeBSD port specifically
asks for the const, presumably for consistency with earlier versions.
