Realy?
But why that?
It cannot be negative.
Using integer instead of unsigned values reduces the possible (positive)

and produces such illogical (to me) compiler warnings.
Delphi compatibility and maximum data size limitation AFAIK (2 GB).
Sigh... all the bad things in FPC crept in from Delphi it seems...
Why did they artifically limit the max number of array elements to 2^31when
it would have been very easy to have a maximum of 2^32 instead?
You have to think back at that time. 64-bit was in the far future, on
Windows you only had 2 GB RAM available to user mode (the 3GB switch was
added with XP AFAIK). So you *could not* allocate more than 2 GB of RAM
even if you wanted to. And you couldn't even reach that, because you
still have other memory in use by the RTL.
The rest is history...
