71 - - Programs should not undefine the macros bool, true, and false,
72 - as C99 lists that as an "obsolescent feature".
74 - Limitations of this substitute, when used in a C89 environment:
76 - - <stdbool.h> must be #included before the '_Bool' type can be used.
78 - - You cannot assume that _Bool is a typedef; it might be a macro.
82 - - In C99, casts and automatic conversions to '_Bool' or 'bool' are
83 - performed in such a way that every nonzero value gets converted
84 - to 'true', and zero gets converted to 'false'. This doesn't work
85 - with this substitute. With this substitute, only the values 0 and 1
86 - give the expected result when converted to _Bool' or 'bool'.
89 - Also, it is suggested that programs use 'bool' rather than '_Bool';
90 - this isn't required, but 'bool' is more common. */
