WinRT detection failed

[anonymous]

I have a normal desktop programm (using VS2012 & Win7x64) but asio think it is a WinRT app (BOOST_ASIO_WINDOWS_RUNTIME is set).

To fix this issue I have to update WinRT detection in boost\asio\detail\config.hpp line 458:

#  if (WINAPI_FAMILY == WINAPI_FAMILY_APP)

instead of

#  if ((WINAPI_FAMILY & WINAPI_PARTITION_APP) != 0)

I suspect the problem is even more complicated, because I also need to ensure the macros in winapifamily.h are defined ahead of the test. As that header is only available from the v8.0 sdk and later, I've enclosed that #include within a test for __cplusplus_winrt.

Can you please try the following and let me know if it works for you:
