Fix WinRT build

[john-peterson]

should boostorg/build be fixed or is this correct?

WinRT detection

with this build command and with /ZW boostorg/build#62 WINAPI_FAMILY_ONE_PARTITION(WINAPI_FAMILY, WINAPI_PARTITION_APP) is false

git clone --depth=1 --no-single-branch http://github.com/boostorg/boost.git .
git checkout boost-1.57.0
git submodule update --init
call "%VS120COMNTOOLS%..\..\vc\vcvarsall.bat" amd64
bootstrap.bat
b2 -j8 toolset=msvc-12.0 address-model=64 variant=release,debug link=shared runtime-link=shared windows-api=store

the macro is in https://github.com/jp9000/OBS/blob/master/extras/winapifamily.h. the detection is discussed in https://svn.boost.org/trac/boost/ticket/9195

name conflict

the name s_addr is already taken https://msdn.microsoft.com/en-us/library/windows/hardware/ff556972(v=vs.85).aspx

D:\file\code\lib\boost\boost/asio/detail/socket_types.hpp(96) : error C2143: syntax error : missing ';' before '.'

this is fixed http://stackoverflow.com/questions/19355634/boost-c-libraries-generating-strange-errors with

#undef s_addr

Closing as this no longer seems to be applicable.
