@eb: Improve portability of iconv handling.

Older NetBSD and SunOS have the traditional iconv prototype with a const
char * argument, while other operating systems are using a char *
argument due to historical accidents in the POSIX standard.

Newer C compiler versions (e.g. GCC 14) have strict enforcement of
pointer type compatibility. Thus a const char * cannot be converted
easily back into a non-const char *. So we need to match the prototype
of the iconv function carefully.
