(0) Or define it thus:-
#define bool char /* or int or short */
enum{false=0,true=1};

but remember that true/false values returned by functions are sometimes other
non-zero values than 1 for `true' or `ran OK', so if x is an int or short or
char containing a yes/no, write if(x) or if(!x), not if(x==true) or the like.

(1) `new ... standard' hereinabove seems to say that the ANSI C++ standard is
still being altered; please what is the email address of the people in charge
of it?
