They are shared.
What exists in as ansistring code in strings is also in sysutils.

We do not invent our own scheme:
We have TP units and Delphi units. The TP units are nearly perfect,
because TP doesn't change any more. The Delphi units were started in the
time that D3 was still the current version, but meanwhile D7 is out and
D8 expected, and the units change sometimes wildly. We simply cannot

This is not correct. The TP object model/language is finished - again,
because TP doesn't change. So we have no work on that any more.
Now, the Delphi language compatibility is being worked on. There the
situation is more complex as Delphi itself still changes. What is more,
there has been feature overlap: FPC had features that delphi didn't
have, and vice versa. Borland seemed to take pleasure in implementing
something that already existed in FPC in a different way in Delphi.

It exists. See ssockets.pp in the FCL.

ICS of Francois Piette - with some minor patches - compiles using FPC.
Synapse as well. The changes have been quite minor - even some potential
bugs in Synapse were discovered and solved.
So finally, I don't think we're doing a bad job. We'll get there, slowly
