- left unchanged if the option is not found.
-
- To have a long-named option do something other than set an `int' to
- a compiled-in constant, such as set a value from `optarg', set the
- option's `flag' field to zero and its `val' field to a nonzero

-/* Usage suggestions:
-
- Programs that use <stdbool.h> should be aware of some limitations
- and standards compliance issues.
-
- Standards compliance:
-
- - <stdbool.h> must be #included before 'bool', 'false', 'true'
- can be used.
-
- - You cannot assume that sizeof (bool) == 1.
-
- - Programs should not undefine the macros bool, true, and false,
- as C99 lists that as an "obsolescent feature".
-
- Limitations of this substitute, when used in a C89 environment:
-
- - <stdbool.h> must be #included before the '_Bool' type can be used.
-
- - You cannot assume that _Bool is a typedef; it might be a macro.
-
- - Bit-fields of type 'bool' are not supported. Portable code
- should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
-
- - In C99, casts and automatic conversions to '_Bool' or 'bool' are
- performed in such a way that every nonzero value gets converted
- to 'true', and zero gets converted to 'false'. This doesn't work
- with this substitute. With this substitute, only the values 0 and 1
- give the expected result when converted to _Bool' or 'bool'.
-
- Also, it is suggested that programs use 'bool' rather than '_Bool';
- this isn't required, but 'bool' is more common. */
