From 13d7728c3df43bdcfb200277273dfb056be07ba3 Mon Sep 17 00:00:00 2001 From: Vince Harron Date: Sun, 24 May 2015 13:24:31 +0000 Subject: [PATCH] Remove log2 dependency when building against Android API-9 SDK Android's API-9 SDK is missing log2 builtins. A previous commit added support for building against this API revision but this requires log2l to be present. (And it doesn't seem to be defined, despite being in the headers.)
