Jan, IMHO, this changes is not correct. Though being of type BIT (which is physically a signed char, hence 8 bit wide), the ordered flags use all 8 bits, only the lowest one (1) indicates sortedness, the highest one (1<<7=128) indicates reverse sortedness, and the remaining ones are "mis-"used for radix clustering. Hence, checking for sortedness shoudl alwasy be done with BAT[ht]ordered(b)&1 --- regardless of the endianess, this should alwasy check for the lowest bit, now matter whether this is located left or right --- anyway, endianess is about byte orde, not about bit order, right?? Hence, if the your change does fix the Itanium problems, than the bug is IMHO caused somewhere else (wrong setting of the ordered flag?), and only appears here...
