I find the suggestion of separate header files a nice idea. We can
restrict system/error_code.hpp to only those interfaces specified for
C++0x, and have a header file for each of the OS-specific namespaces
(with the same name as the namespace for convenience), i.e.
system/cygwin_error.hpp, and so on. Developers have to use the
OS-specific namespace qualification to refer to those error codes
anyway, so it doesn't seem like much extra burden to include the
additional header file.
