+Subject: [PATCH 6/6] unix/configure: borrow the LFS test from autotools.
+
+Infozip's LFS check can't work for cross-compilation
+since it try to run a target's binary on the host system.
+
+Instead, use to LFS test used by autotools which is a
+compilation test.
+(see autotools/lib/autoconf/specific.m4)

+Subject: [PATCH] make encrypted archives reproducible
+
+Zip always try to generate new encryption header depending on execution
+time and process id, which is far from being reproducible. This commit
+changes the zip srand() seed to a predictable value to generate
+reproducible random bytes for the encryption header. This will compromise
+the goal of secure archive encryption, but it would not be a big problem
+for our purpose.
