Re: INT_MIN and compiler diagnostic

When I compile this using gcc, I get a diagnostic on line 7:

[pcg@mylinux test]$gcc -ansi -pedantic -Wall -o /tmp/x /tmp/x.c
/tmp/x.c: In function `main':
/tmp/x.c:7: warning: this decimal constant is unsigned only in ISO C90

On mine (Sun sparc) using gcc with exactly the same flags I get

x.c:7: warning: decimal constant is so large that it is unsigned

The program output is:

INT_MAX = 2147483647 INT_MIN = -2147483648
x = -2147483648 y = -2147483648

So amusingly, it tells me the constant is unsigned, then prints it
signed.

Where's a language lawyer when you need one?!
