In the math unit are the CompareValue functions only for signed integers. Why not
for DWORD and QWORD?
I guess, that it's Delphi mimicing implementation (because it is Delphi-like).
And it can be tricky to distinguish signed and unsigned expression values.
Like,
a: qword;
a-1 --- ??? (anyone may know for sure that a-1>0 and want to subtract one)
I guess it's something like that.
If you check <http://www.freepascal.org/mantis/view.php?id=8448> you can
see this bug in action - the fpcadds and math unit provide signed and
unsigned versions of CompareValue, but the correct one is not always chosen.
