((*Signed integer overflow is undefined behavior in C. Many compilers 
assume no signed integer overflows and even optimize away overflow 
checks. The -fno-strict-overflow flag works around this issue in gcc, 
but doesn't fix the fundamentally broken code.*))

((*This patchset fixes signed integer overflows in time.c, ossl.c, and 
bigdecimal.c.*))

I've attached the associated patch.
