-/* Authors of new ports of the GNU C Library must override this file
- with their own bits/errno.h in an appropriate subdirectory of
- sysdeps/. Its function is to define all of the error constants
- from C2011 and POSIX.1-2008, with values appropriate to the
- operating system, and any additional OS-specific error constants.

- C2011 requires all error constants to be object-like macros that
- expand to "integer constant expressions with type int, positive
- values, and suitable for use in #if directives". Moreover, all of
- their names must begin with a capital E, followed immediately by
- either another capital letter, or a digit. It is OK to define
- macros that are not error constants, but only in the implementation
- namespace.

- errno.h is sometimes included from assembly language. Therefore,
- when __ASSEMBLER__ is defined, bits/errno.h may only define macros;
- it may not make any other kind of C declaration or definition.
- Also, the error constants should, if at all possible, expand to
- simple decimal or hexadecimal numbers. */
