[issue1621] Python should compile with -Wstrict-overflow when using gcc

[Martin v. Löwis]

Martin v. Löwis added the comment:

Using ansi is out of scope of this issue, and should not be mixed with
it. -ansi is about disabling certain GCC extensions. This report is
about C code in Python which has undefined behavior.

I think there is disagreement on whether Python should stop relying on
this particular undefined behavior (namely, whether the sum of two large
positive numbers is negative). GvR (apparently) believes that the
compiler should guarantee that the twos-complement semantic is available
throughout the C language.
