Some known missing functionality:
1 implements style delegation
2 vararray support is patchy.
3 customvariants are missing in the rtl
4 packages
5 dispinterfaces and dispid.
6 assembler routines have some constructs that are not supported.
Can you tell which one(s) are missing then ?
Mostly caused by number 2, 3, and 6.
I don't get it. Variant support (after using variants unit) works
good, custom variants is a mistery for me right now and assembler
routines are not to be used in end-classes/methods/functions because of
portability issues. Other thing is with the dispinterfaces and
interfaces at all. The DO WORK perfectly in delphi but they are more
than tricky in FPC (even though the support for interfaces has been
greatly improved in 2.0). So in my opinion interfaces (which are the
one-and-only) possibility for exporting classes from DLLs should be
the most important thing to fix.
Besides I find that FPC 2.0 makes the executables just to big.+
The rtl is slightly bigger because of the portability layers and an
optimizer aligning code for modern CPUs but upx makes them definitily
smaller than D. ones:

IIRC Delphi creates 16 kB something.
Even
though I compressed them with UPX -9 they are still bigger than the one
compiled with delphi. This is the one thing I really dislike in
freepascal. Besides the lack of real working interfaces I find FPC my
favourite pascal compiler.

Matthias.
