the users must compile the RTL for non Lazarus use.
=============
Really , it needs  FPC sources at user's side.

Then  a workaround - to maintain protected properties for private variables :

private
 fldPrivate1: integer;
 fldPrivate2: string;
[..]
private
  prorerty Private1: integer read fldPrivate1 write fldPrivate1;
  prorerty Private2: integer read fldPrivate2 write fldPrivate2;
protected
  prorerty Private1relaxed: integer read fldPrivate1 write fldPrivate1;

Then MSEgui/FPgui may rely on Private1relaxed insted of fldPrivate1+cracker.

Once a cracker disabled, all related fldPrivate(N) needing replacement
with Private(N)relaxed will be revealed at 1-st compilation.
