diff src/stdlib/SDL_iconv.c @ 3985:2f8efcf14c83 SDL-1.2

Okay, apparently the newer standard specifies char** for the inbuf parameter to iconv() (See http://lists.debian.org/debian-glibc/2004/05/msg00006.html) I'm casting in the general case, but I added a non-const codepath in case it matters on some platform.
