Standards compliance: - 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: - 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'. - C99 allows the use of (_Bool)0.0 in constant expressions, but this substitute cannot always provide this property. Also, it is suggested that programs use 'bool' rather than '_Bool'; this isn't required, but 'bool' is more common. */ /* 7.16.
