//The stuff in this file somewhat protects us from the fact that some
//platforms may not put stream-related stuff in the std namespace,
//even though most do.
//These days (2007) perhaps all platforms do put everything in std and
//perhaps no platforms still have iostream.h without having <iostream>, etc.
//But historically we've had to account for these possibilities and I see
//little to be gained from removing this flexibility at this point.
//
//The basic mechanism here is to use macros that are defined differently
//for certain situations. An alternative approach would be to import
//symbols into our namespace, but we choose not to do that since it is
//a well-known sin to perform namespace pollution from within a header.
