UNICODE is now reserved for Delphiunicode mode afaik. So we use
FPC_OS_UNICODE as global define to signal that FPC expects API units in
two-byte value. (because there is simply more Delphi code that tests for
2009+ with unicode than 3rd party API units)

In headers that already have unicode we've added 
{$IFDEF FPC_OS_UNICODE}{$define unicode} {$endif}
 to the top, since that is local only.

This will get hard in places where FPC/Lazarus redefines API structures for
own purposes. E.g. if you fix this,  further down it redefines wndclass.
