Hello,
As of tomorrow, the 1.1 snapshot will have a rewritten constant handling.
Since the support for 64bit constants was introduced in 1.1, all hex
constants > $7fffffff were sign extended (so if you wrote $80000000, it
was actually interpreted as $ffffffff80000000).
This is now fixed, but the result is that those numbers between $80000000
and $ffffffff (when using the hex notation) are now cardinals instead of
longints. As such, you will get range check errors (when using -Cr) if
you try to pass such a value as a longint paramter. Use an explicit
longint() typecast to overcome this (you'll still ge a warning though)
