glibc-devel-2.2.4-19:/usr/include/iconv.h contains:

extern size_t iconv (iconv_t __cd, char **__restrict __inbuf,
                      size_t *__restrict __inbytesleft,
                      char **__restrict __outbuf,
                      size_t *__restrict __outbytesleft);

I do not know what '__restrict' means (anybody knows?) but it does not 
appear to be equivalent to 'const'.
