New description:

 The new compiler that comes with XCode 5 is failing with :

 {{{
 #warning Use of the header <ext/hash_map> is deprecated.
 }}}

 This variant disables fatal warnings  (`-Werror`) so users can continue to
 build until the next release with the fixes is out.

Comment:

 ola @0.9.2 fails to build on the 10.7 and 10.8 buildslaves, with this
 error:

 {{{
 clang: error: argument unused during compilation: '-pthread'
 }}}

 An unused argument would normally only be a warning, but `-Werror` is
 turning the warning into an error.

 I've disabled the use of `-Werror` in r124835.
