The packages that break with vanilla zlib 220.127.116.11 (like Lynx, which I
fixed myself and sent upstream) are less than those that break with r1
and r2. So that argument doesn't hold. Also, you didn't rebuild the
whole tree, so there's no way of knowing whether there's 13 packages
that break or 130.

If vapier is such an expert, why did he use _Z_ as the prefix for those
macros? It's a well known fact that identifiers beginning with an
underscore and followed by a capital letter (or another underscore) are
reserved in C and shouldn't be used.

Introducing something to the tree that is known to break packages means
it's better to mask it. On top of that, zlib 18.104.22.168 is a beta version,
which supports masking more strongly when you combine it with the breakage.

If upstream accepts the changes, then that's good work. But not when
doing that with an unmasked package. ~arch is for testing. We tested.
Now we know it's borked, so mask it. When it looks ready, unmask it
for another round of wide testing.

But we *did* fuck with upstream's release.
