Delphi unit status list
Here I keep some notes about which Delphi units are not or not completely supported by FPC/Lazarus.
If you know in what version they were added don't hesitate to annotate them with D6+ or so.
Strutils - Large parts done, but not very optimal. (further improvement done post 2.0.0, lots of extensions too)
dateutils - Looks reasonably complete
convutils - Basic unit convert functions implemented. Couldn't find much docs on the net about this unit.
Masks - (TExprParser?) Don't know what this does, but it is missing.
dbcommon - missing, but maybe this is stuff factored out from unit db.
variants - implemented, but a lot of the wrapper classes ( TPublishablevarianttype, TInvokablevarianttype etc) are either not existing, or have a lot of missing methods.
sqltimst - doesn't exist
