[issue11501] distutils.archive_util should handle absence of zlib module

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

Thanks.  One question: why not using a clause like “if zlib is not None” instead of catching a RuntimeError?  The if test looks more specific to me, whereas the RuntimeError might come from something else, and thus shouldn’t always e ignored.

In the patch function, I would not use assert but hasattr and a real exception (so that the behavior does not change when run under python -O).
