Hello:

I have a problem using the shift operator, maybe a bug (ok, a bug or i'm wrong 
about shift operator)

System: i386-redhat-linux
Version: Gcc 3.4.5
Case:
 In the next snipplet:
unsigned int getMask(int n){
unsigned int mask = 0;
a = ~(~(a)<<n);
}

In case of n<32, the function works correct but if n=32, the value of a is 0 
(when should be 0xFFFF).

Thanks in advance
Juan
