Review for RT-38725

[Danno Ferrin]

Kevin, Stephen, and anyone running Mac OSX 10.8 (Mountain Lion) with XCode 5.1.1

This patch should get the new launcher building on 10.7, 10.8, and 10.9 (and 10.10 maybe when it is released).  However, we don't have anyone running Mountain Lion and/or XCode 5.1.1. The XCode issue is the more imprtaint one since JDK 9 appears to be moving to 5.1.1/clang on a 10.9 build machine, possibly with 10.8 SDK.  

Is there anyone on this list running either Mountain Lion or XCode 5.1.1 that could test this theory out?

It's verified on 10.7.5 with XCode 4.5 and 10.9.5 with XCode 6 with either the 10.7 or 10.9 sdk.
