+Subject: [PATCH] Fix no-ZLib builds.
+
+Don't use ZLib routines or data types if we're built without ZLib.
+
+Don't support --compress-type=gzip, or a gzip check box in the Output
+pane of the Capture Options dialog, if we're built without ZLib.
+
+Fixes #17899.
+
+
+(cherry picked from commit 125f5cbd881c2e1236d968a3e8fdcf5af2606e77)
