[Lazarus] Were olectrls and stdvcl replaced in Lazarus?

[Luciano de Souza]

Hello all,

An old project was initially compiled with Turbopascal. Afterwards, it 
was converted to Delphi. Now, I am trying to compile it using 
Freepascal. The {$mode delphi} is a very good feature, but it does not 
solved my problem totally because two units were not found.
For this reason, I ask: regarding olectrls e stdvcl were not found, 
which units have replaced them in Lazarus?
Regards,
Luciano
