Many values in the spec are "dword" while signed values are assigned to them (usually -1 as special value).

This causes problems in FPC when people compile with extra runtime checks (that check ranges strictly). We can adjust the typing to signed (but that is a specification discrepancy), hence we decided to ask this upstream.

We can also disable checks for those units. (in theory we can also typecast each and every assignment but that is too painfull), but that is not so elegant.

Possible solutions: adapt types, or define the <0 cases not as -1 but as dword(-1) or $FFFFFFFF
