Not at all - in C, (this has changed recently due to standardisation etc...I think, although depends on the compiler rev that you use) you never had a boolean datatype as such, therefore you would always define a BOOL datatype as an integer.  These days, you actually have a bool datatype (as you would do in C++) so you might re-write this or not define the macro in the first place. 

 

Defining a boolean type in this way, means you can do all kinds of stuff like the classic if

 

(!somefunc()){ etc...

 

without the compiler puking everywhere.

 

Cheers
