From 3747e27470bbbe7814c461cc08721134042edf4f Mon Sep 17 00:00:00 2001 From: kientzle Date: Sun, 24 Apr 2005 22:04:34 +0000 Subject: Update zconf.h and gzio.c with changes from ZLib 1.2.1 to ZLib 1.2.2. These are two of the three files that have non-trivial differences from the vendor branch. minigzip.c is the third, but there were no changes from ZLib 1.2.1 to ZLib 1.2.2 in that file. The rest of the files I intend to get reverted back to the vendor branch (with cooperation of cvsadmin@).
