I answered already on 27th October. In case you missed it here's my answer
again:

A property must have at least a read or a write accessor if it isn't
inherited, so you need to add at least one of them. Since that is the
standard form for properties FPC supports this since the "default" keyword
for properties is supported.

Sven
