Thanks for your patience, I'm not meaning to go off topic,
just to discover exactly what gcc does with -fno-strict-aliasing:
I think that is itself on-topic: I don't see any other place
I could find out (other than reading all the code myself,
which is a rather daunting task :)
Anyhow I'm satisfied with the answers, thanks again everyone
who commented.
Just for context: my current interest is learning about
exactly what optimisations gcc/g++ does and doesn't
do in what circumstances, because I have a compiler
which generates C++: to get my compiler to generate
fast code, I have to know what kind of code g++ likes
and what it doesn't handle so well.
Again, thanks for your patience.
