+/* 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. */

+ 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
