Dear rms:

I believe the code below demonstrates a generic bug with gcc 1.36.
It is at least a problem on sparc where I built gcc 1.36.
It prints "false, true" when it should print "false, false."  Note
the second if clause is the problematic one, I include the first
simply to illustrate the inconsistency.

I spent some time in dbx working on this.  The problem almost certainly
has to do with the routine shorten_compare() but I can't quite pin
it down.  Please let me know if there is a simple fix.

Thank you.

{
    char i = 1;

    if ( i < -128 )
	printf("true, ");
    else

    if ( j < -2147483648 )
	printf("true\n");
    else
	printf("false\n");
