[boost] [boost.python] GCC >=4 "-fvisibility=hidden" patch

From: Jason Kankiewicz (jkankiewicz_at_[hidden])
Date: 2005-11-29 16:27:25

Boost.Python's sources only deal with GCC's "-fvisibility=hidden" option 
  for versions [3.5 - 3.9]. It should also work properly when built with 
GCC 4 and higher. The attached patches to boost/python/detail/config.hpp 
and boost/python/module_init.hpp enable it to do so.

Tested with GCC 4.0 (XCode 2.2) on OSX 10.4.3 (Tiger).
