From a7bd33957e099dea109e219a348b131c7186ee1e Mon Sep 17 00:00:00 2001 From: Peter Korsgaard <jacmet@sunsite.dk> Date: Mon, 14 Mar 2011 09:48:13 +0100 Subject: [PATCH 04/16] alsamixer: fix build on uClibc exp10 is a glibc extension, which isn't supported on uClibc. Luckily, exp10() is trivial to compute based on exp(), so add a wrapper for the uClibc case.
