GNU libiconv and GNU libc are mutually independent.

This is generated from libiconv-1.9.1/include/iconv.h.in:

extern size_t iconv (iconv_t cd, @ICONV_CONST@ char* * inbuf, size_t *inbytesleft, char* * outbuf, size_t *outbytesleft);

It seems that:

(A) @ICONV_CONST@ follows the system's iconv.h if it exists, or
(B) @ICONV_CONST@ is empty (non-const) by default.
