[EGCS 2.96, 2000/01/17 snapshot] Bad assembly code

[Marco Goetze]

The attached file "bug.c" makes the compiler emit code erroneous in that

  bug.c:0: #define VAL (1<<7)
  bug.c:7: if (i & VAL) {

is compiled (via `gcc -S -g bug.c`) as

  bug.s:44: andl    $-128, %eax

which should be $128 (0xffffff80 vs. 0x00000080), since "(1<<7)" is a 
type int expression (-128 would have been the correct value if VAL was 
of type signed char).  Note: this also happened with the 2000/01/03
snapshot.

Attaching both "bug.c" and "bug.s".
