I think GCC never warns about this, like most compilers.
Microsoft's compiler does, if its warning level is set to the highest.
But that's usually too annoying, since it also warns against codes
like this:
char c;
if((c=getchar())>='A' && c<='Z') //warning: getchar returns int
c += 'a'-'A'; //warning: c+('a'-'A') has type int
You'll have to use explicit casts to suppress them.
