#define TRUE (1 == 1) <= ow my eyes

#define boolean int <= what ?

now in my college they took a different approach :

(found in a C source file we had to work on on C classes)

typedef enum{FAUX=0, Faux=0, faux=0, FALSE=0, False=0, false=0,
         VRAI=1, Vrai=1, vrai=1, TRUE=1,  True=1,  true=1} Booleen;

Not only  they managed to handle the personal preferences of everybody.  They also happened to provide both French and English wordings.

I find this a bit odd since they only defined Booleen and no Boolean. (not even speaking about BOOLEAN, booleen ...)
