[issue1621] Do not assume signed integer overflow behavior

[STINNER Victor]

Thank you very much to the task force who worked on this issues which can be seen as boring and useless, but are very important nowadays with C compilers which are more and more agressive to optimize everything (I'm looking at you clang!).

This bug is open for 11 years and dozens and dozens of undefined behaviours have been fixed in the meanwhile.

This bug is a giant beast with many patches and many pull requests. I dislike such bug, it's very hard to follow them. I suggest to open new bugs for undefined behaviour on specific functions, rather than a very vague "let's open a single bug to track everything".

It's now time to close the issue.

----------
resolution:  -> fixed
stage: patch review -> resolved
status: open -> closed
