    By default, 0 is equal to untrue.  If you test a value, such as
 a pointer, the conditional will be true for any nonzero value.

    if(myPointer) free(myPointer);

 This will only call free when myPointer has a nonzero value.  To
 be consistent and take advantage of this, you should define TRUE
 as 1 and FALSE as 0.  If all of your conditionals will test for
 TRUE or FALSE explicitly, then it doesn't matter, really, except
 that it is counter-intuitive for the C environment.
