The OpenBSD compiler checks that the source array boundary isn't exceeded,
using sig_Signature[1] causes the compiler to warn and halt building with an
error in this line
memcpy(sig20->sig_Signature, NSPR_SIGSTR_V20, sizeof(NSPR_SIGSTR_V20));
a size of 56 has been given NSPR_SIGSIZE_V20 in the same way as
nspr_signature_v10. But could be set to sizeof(NSPR_SIGSTR_V20).
