Well, I've installed Donn Seeley's fix for the C compiler screwing up on
initializing shifted, unsigned variables, and found out a nasty side effect:
The (unsigned) cast is IGNORED!  This is my program:

	main()                          
	{       int big_number = ((~((unsigned) 0)) >> 1);
		printf("this is a big number: %d\n",big_number);
	}                               

Before installing the fix the program produced this output:

	this is a big number: 2147483647

(To remind the original problem: should big_number be declared as static or
as a global variable, C compiler would blow up and go into a loop).
After installing the fix, I got the following output:

	this is a big number: -1

Sigh....
