That's done in several existing libraries.

Try to limit inclusion of platform dependent headers to implementation 
(.cpp) files; don't include platform dependent headers from the public 
boost headers.

That isn't always possible, but a lot of users find inclusion of headers 
like <windows.h> to be very distasteful, and don't like to get such headers 
as a side effect of including a boost header.
