/* 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.

       - 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.  */


/* 7.16. Boolean type and values */

/* 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'.  */
#if defined __cplusplus
  /* Assume the compiler has 'bool' and '_Bool'.  */
#else
   /* If @HAVE__BOOL@:
        Some HP-UX cc and AIX IBM C compiler versions have compiler bugs when
        the built-in _Bool type is used.  See
          http://gcc.gnu.org/ml/gcc-patches/2003-12/msg02303.html
          http://lists.gnu.org/archive/html/bug-coreutils/2005-11/msg00161.html
          http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html
        Similar bugs are likely with other compilers as well; this file
        wouldn't be used if <stdbool.h> was working.
        So we override the _Bool type.
      If !@HAVE__BOOL@:
        Need to define _Bool ourselves. As 'signed char' or as an enum type?
        Use of a typedef, with SunPRO C, leads to a stupid
          "warning: _Bool is a keyword in ISO C99".
        Use of an enum type, with IRIX cc, leads to a stupid
          "warning(1185): enumerated type mixed with another type".
        Even the existence of an enum type, without a typedef,
          "Invalid enumerator. (badenum)" with HP-UX cc on Tru64.
        The only benefit of the enum, debuggability, is not important
        with these compilers.  So use 'signed char' and no enum.  */
