silence warnings when using zaphod32 on 64 bit builds
if STRLEN is 64 bit, then there is truncation when using key_len to initialize the state.
This causes problems with windows compilers especially. See comments from bulk88 in
perl #132860 (which is not directly related to this patch, but is where it was discussed)
