The integer types are automatically casted, no matter if
you compare (int) or (char) to a numerical or character
value.

int i;
char c;

if(i == 32 || i == ' ') ...
if(c == 32 || c == ' ') ...

Functions or macros that deal with characters usually
do return (int), even though one would expect (char).
