Here is an example for the changes in rawmd5.

extern struct fmt_main fmt_rawMD5unicode

static void rawmd5_init(void)
{
	if (options.flags & FLG_UTF8)
		rawMD5unicode.set_key = set_key_utf8;
	else
		rawMD5unicode.set_key = set_key_ansi;
}


Simply sets the function pointer to the proper set_key into the format's
function pointer for set_key.  The only reason for the extern, is since the
declaration/definition of the actual object is at the end of the source
file.
