# Use "-fwrapv" option to tell compiler that the code is written assuming that
# signed arithmetic is implemented using the twos-complement representation
# (this is pretty much universally true on today's processors).
# <http://gcc.gnu.org/onlinedocs/gcc-4.2.1/gcc/Code-Gen-Options.html>
# Without this option, gcc may decide that because the C language
# does not require processors to use twos-complement representation, that means
# gcc is free to do some "creative" optimizations that don't preserve the overflow
# behaviour of twos-complement arithmetic. See also "-fstrict-overflow":
