For example:

  {$IF defined(FPC)}
    TMemIniFile.Create(IFile);
  {$ElseIf CompilerVersion >= 20} {Delphi 2009 = 20..}
    TMemIniFile.Create(IFile, TEncoding.UTF8);
  {$ELSE}
    TMemIniFile.Create(IFile);
  {$IFEND}

CompilerVersion is only defined by the Delphi compiler.
An undefined macro is by default an empty string.
FPC uses FPC_FullVersion.
