You aren't importing from a DLL, so Win32 has the same rules.

The problem is that the interface declaration sets the assembler name to
something like U_UNITNAME_DFCRAP$TSO. The implementation declaration
changes the assembler name to _dfCrap. This gives problems when the
procedure was already called (from other units) before the implementation
declaration is parsed.
