I understand that and that's why my first sentence was: This is not
something that is absolutely necessary.

We often say that we don't want to reproduce 'ugly stuff from glibc
etc.' (eg. __progname). This does not change the fact that a lot of
code will require patches to fix __progname problem. If Rich has taken
the effort to rewrite/fix libc, we can fix __progname... if needed
(it's really small patch.. discussed on the list).
