[Boost-users] Erorr compiling application with boost 1.43.0 on WinXp/VS2008

Hello everybody,   I am developing some application on Visual Studio 2008. I am working on Windows XP (sp3) and our minimim requirement platform for the applcation is also WinXp. I downloaded and compiled the lasta boost version (1.43.0).     However, when compiling the application I'm getting this error:   C:\Boost\1.43.0\boost/asio/detail/win_fenced_block.hpp(48) : error C3861: 'MemoryBarrier': identifier not found   It looks like the MSVC wants to build it as a Vista application since according to http://msdn.microsoft.com/en-us/library/ms684208%28VS.85%29.aspx minimum supported client for MemoryBarrier(void) is Windows Vista.   What would be the proper fix for this issue?   Thanks, Ovidiu
