-Wstrict-aliasing warns for all aliasing problems that we can detect, and which
are obviously incorrect.
-Wstrict-aliasing=2 warns for all aliasing problems that we can detect, and
which are not obviously correct. Thus -Wstrict-aliasing=2 catches more problems
than -Wstrict-aliasing, i.e. the ambiguous ones, but will also sometimes warn
for cases that are technically OK.
-Wstrict-aliasing=2 will report all aliasing prolems that we can detect, but
obviously, neither one can warn about aliasing problems that we can't detect,
and hence neither one can catch all possible cases. So I see that the "all" in
the docs is misleading. I will rewrite.
