[9fans] another compiler bug (another try to send this coherently)

[Mike Haertel <mike@ducky.net>]

Argh, the wrong stuff got pasted on the last try and it included a ^D.

This program illustrates that the integral promotions
of types smaller than int will incorrectly promote unsigned
char to unsigned int, rather than signed int as required
by ANSI C.

On a conforming implementation with 32-bit ints, this
program should print "-1 -1".

#include <stdio.h>
#include <stdlib.h>

int
main()
{
	static unsigned char tab[1] = { 0x80 };
	static int x = 0x80;

	printf("%d %d\n", tab[0] << 24 >> 31, x << 24 >> 31);
	exit(EXIT_SUCCESS);
}
