wxWidgets/include/wx/platform.h
Vadim Zeitlin e87d78bb36 Move wx/msw/gccpriv.h inclusion back to wx/platform.h from wx/compiler.h. 
Do keep compiler-specific wxCHECK_MINGW32_VERSION() in wx/compiler.h as it's
needed by wx/cpp.h which includes wx/compiler.h only. But put the rest of the
stuff in gccpriv.h in its old place as including it before wx/setup.h didn't
work correctly and was unnecessary anyhow.

__WXOSX_OR_COCOA__ is a common define to wxOSX (Carbon or Cocoa) and wxCocoa ports under OS X.
DO NOT use this define in base library code. Although wxMac has its own
private base library (and thus __WXOSX_OR_COCOA__,__WXMAC__ and related defines are
valid there), wxCocoa shares its library with other ports like wxGTK and wxX11.
To keep wx authors from screwing this up, only enable __WXOSX_OR_COCOA__ for wxCocoa when
not compiling the base library. We determine this by first checking if
wxUSE_BASE is not defined. If it is not defined, then we're not buildling
the base library, and possibly not building wx at all (but actually building
user code that's using wx). If it is defined then we must check to make sure
it is not true. If it is true, we're building base.
If you want it in the common darwin base library then use __DARWIN__. You
can use any Darwin-available libraries like CoreFoundation but please avoid
using OS X libraries like Carbon or CoreServices.
