/* Until libstdc++ for gcc 4.2 is released, we have to declare all
 * symbols in libstdc++.so externally visible, otherwise we end up
 * with them marked as hidden by -fvisible=hidden.
 *
 * See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20218
 *
 * Due to a more strict linker included with Xcode 4, this is disabled on Mac OS X and iOS.
 * The reason? It changes the visibility of Boost functions.  The mismatch between visibility Boost when used in Ogre (default)
 * and Boost when compiled (hidden) results in mysterious link errors such as "Bad codegen, pointer diff".
