commit 7f4c1c5aa6c4b8dce6fc98bfd0f161a5ff7d2492
Author: Lawrence Sebald <ljs...@us...>
Date: Sun Nov 17 21:38:46 2013 -0500
 A few changes/updates to dc-chain:
 1. Update GCC version to 4.8.2.
 2. Automatically build GCC's dependencies along with GCC.
 3. Add in a small fix for OS X Mavericks (GCC can't be built against libc++).
