Dear David,

Many thanks for your prompt and helpful response.

Ah yes, seen, thanks. So this is a line-based approach actually.
I'm wondering whether code has already been written implement a
block-based approach, i.e. an aproach where one can make several lines
compiler-version dependent at once?

Seen also, thanks.

I guess it would also be okay,in a tool, to use that same test and to
just rpovide the bytes module if it does not exist, rather than
installing a package...

Thanks!
Sébastien.
