[fpc-pascal] class abstract

[ik]

Hello,

I have two questions regarding class Abstract:

1. From what version of FPC does it support ?
2. Can I inherit from a class and the new class that I declare can be set as
abstract ?

I mean

TClassA = class abstract
...
end;

TClassB = Class(TClassA) abstract ?

If so, then what am I missing here? FPC (2.5.1) tell me that it is expecting
":", but "abstract" was found.

Thanks,
Ido
