Is it possible to use MFC's message mapping macros without Microsoft's extensions to the C++ language?
I'm having some troubles, for example with Clang:
Code:error: call to non-static member function without an object argument ON_MESSAGE(WM_UPDATEUISTATE, OnUpdateUIState) ^ C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.11.25503\atlmfc\include\afxmsg_.h expanded from macro 'ON_MESSAGE' (memberFxn)) }, ^
