Not needed by you perhaps. The Registry unit also provides the 
TRegIniFile out of Delphi compatiblity which is a TIniFile descendant of 
which the name value pairs are stored in the registry.

You install the FPC distribution once and then you have access to all 
the units provided with FPC. And in normal cases the compiler will 
recognize if you don't use certain code or certain classes in a unit and 
then it will not link in the corresponding code (e.g. the TRegIniFile 
mentioned above will not be in your final executable if you don't use 
it). The compiler needs all used units however during the parsing phase 
to check whether everything is ok.

You need to give explicit examples and what compiler options you used. 
These can make a big difference.

Yes, it is simple.
