Did you encounter an issue in practice?  It’s only a problem for static
linking.

I’m asking partly because 452 packages would need to be rebuilt.

Yes, zlib is required for libxklavier (it not use zlib but libxml2).
I try libxklavier with '--disable-static', but '-lz' is still there.

Ah, in this case, I think add 'zlib' to libxklavier should be ok?

Hmm, OK.

Yeah, but your initial patch really is the right fix.  So let’s push it.

Thanks,
