According to the C++ Draft WP, 'bool' is a C++ built-in type with the
two values 'true' and 'false'. Beginning with gcc-2.6.? the type bool
is supported by gcc. You should be aware that there are more keywords
in C++ than in C.  It is correct that some will of the introduced
keywords break existing code.  Especially, the keywords introduced into
C++ after the ARM was released.
