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.

main()
{
char i = 1;
int j = 1;
if ( i < -128 )
printf("true, ");
else
printf("false, ");
if ( j < -2147483648 )
printf("true\n");
else
printf("false\n");
}
