// values. This code should not have to pay the cost of distinguishing
// between categories, since it is not yet known if that is needed.
//
// * Users wishing to write system-specific code should be given enums for
// at least the common error cases.
//
// * System specific code should fail at compile time if moved to another
// operating system.
// The system specific portions of the interface are located in headers
// with names reflecting the operating system. For example,
//
// <boost/system/cygwin_error.hpp>
// <boost/system/linux_error.hpp>
// <boost/system/windows_error.hpp>
