Drop support for old Delphi?

[Alexey-T]

{$IFDEF D3} {$DEFINE UseAsserts} {$ENDIF}
{$IFDEF FPC} {$DEFINE UseAsserts} {$ENDIF}
// Define 'use subroutine parameters default values' option (do not edit this definition).
{$IFDEF D4} {$DEFINE DefParam} {$ENDIF}
{$IFDEF FPC} {$DEFINE DefParam} {$ENDIF}
// Define 'OverMeth' options, to use method overloading (do not edit this definitions).
{$IFDEF D5} {$DEFINE OverMeth} {$ENDIF}
{$IFDEF FPC} {$DEFINE OverMeth} {$ENDIF}

it's not good, maybe drop D5 and older? D4 and older? code not nice with ifdefs.

What exactly is the problem?
We have very simple and easy to understand piece of code.

I agree there is little sense to suppost Delphi before 7.
But what's the harm in this code?
