//
// While std::error_code works OK on all platforms we use, there are some
// some problems with std::errc that can be avoided by using our own
// enumeration:
//
// * std::errc is a namespace in some implementations. That means that ADL
//   doesn't work and it is sometimes necessary to write std::make_error_code
//   or in templates:
//   using std::make_error_code;
//   make_error_code(...);
//
//   with this enum it is safe to always just use make_error_code.
//
// * Some implementations define fewer names than others. This header has
//   the intersection of all the ones we support.
//
// * std::errc is just marked with is_error_condition_enum. This means that
//   common patterns like AnErrorCode == errc::no_such_file_or_directory take
//   4 virtual calls instead of two comparisons.
