Consider this following simple app:
#include
#include
#include
int main() {
return 0;
}
If you try to build that on Windows, you receive the following error:

If asio.hpp is moved ahead of the thread headers, the error goes away. We've been trying to dictate #include order to work around this problem, but it keeps cropping up.
