New submission from Jeremy Kloth <[email protected]>:
The latest zlib (1.2.12) introduces 3 new compiler warnings. Now being an
external library, I do not think we generally patch them, so I propose to
simply silence the warnings for the offending file.
For reference, the problem comes from:
--- deflate.h.old 2022-04-05 11:27:26.869042900 -0600
+++ deflate.h.new 2022-04-05 11:26:11.512039600 -0600
