Since Lazarus requires 2.6.0 anyway one could change that to use normal 
class helpers:

type
   TWinControlHelper = class helper for TWinControl
     function GetWinControlFlags: TWinControlFlags; inline; // I hope 
inline works in that case, if not one might consider it as a bug and 
report it :)
   end;

function TWinControlHelper.GetWinControlFlags: TWinControlFlags;
begin
   Result := FWinControlFlags;
end;

And then where TWinControlAccess was used:

if not (wcfInitializing in ABitBtn.GetWinControlFlags) and BuildNeeded then
   ...

Note: The code was not tested, but it *should* work.
