#define _STDBOOL_H

/* ISO C 99 <stdbool.h> for platforms that lack it.  */

/* 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.

       - 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.  */

/* For the sake of symbolic names in gdb, we define true and false as
   enum constants, not only as macros.
   It is tempting to write
      typedef enum { false = 0, true = 1 } _Bool;
   so that gdb prints values of type 'bool' symbolically. But if we do
   this, values of type '_Bool' may promote to 'int' or 'unsigned int'
   (see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'
   (see ISO C 99 6.3.1.1.(2)).  So we add a negative value to the
   enum; this ensures that '_Bool' promotes to 'int'.  */
