+Subject: [PATCH] libtool: rework revision to fix OS X breakage
+
+It seems the OS X linker restricts the revision field to 8 bits.
+Rework how we calculate that value and pack it in closer to fit.
+It might produce some collisions if we get to like 2.2.8, but oh
+well ... this field doesn't need to be super exact.
+
+Fixes #214 and fixes #241.
