Hi everyone,
I'm using Boost 1.39, and I'm getting the following linker errors on MSVC9:

MainWindow.obj : error LNK2019: unresolved external symbol
"__declspec(dllimport) class boost::system::error_category const & __cdecl
boost::system::get_system_category(void)" (__imp_?get_system_category_at_system

boost::system::`dynamic initializer for 'system_category''(void)"

The issues above don't really make any sense. The calling convention,
according to the information above, is __cdecl, and in my project settings
I'm using cdecl as well. I found several posts about this on the mailing
list but no solutions were offered that I could see. How can I resolve these
issues? Note that I am using static libraries.
