about those clang warnings

[René J.V. Bertin]

Hi,

Concerning commits  e8cc6f193c5a0762b65b3381aca3e325b16280f0 and 0cbe5074b6e3be0b52dcb339959b57da144529dd:

for what clang (platform) versions are the added options? The system clang yells about them on OS X 10.9 (that's a 3.6 version).
Also, the add_definitions("-DQ_COMPILER_INITIALIZER_LISTS=1") line is no longer necessary (and probably counterproductive, I can't remember) with Qt 4.8.7 .
