【Delphi】 Delphi 编译器版本号对照
判断当前 Delphi 的运行库版本：
procedure TForm1.FormCreate(Sender: TObject);
begin
ShowMessage(FloatToStr(System.CompilerVersion));
end;
编译时可以判断版本号:
{$IF CompilerVersion >= 18.5}
//some code only compiled for Delphi 2007 and later
{$IFEND}
{$IFDEF CONDITIONALEXPRESSIONS}
{$IF CompilerVersion >= 17.0}
{$DEFINE HAS_INLINE}
{$IFEND}
{$IF RTLVersion >= 14.0}
{$DEFINE HAS_ERROUTPUT}
{$IFEND}
{$ENDIF}
{$if defined(FPC) or defined(VER170) or defined(VER180) or defined(VER190)
or defined(VER200) or defined(VER210) or defined(VER220) or defined(VER230)
or defined(VER240) or defined(VER250) or defined(VER260)}
{$DEFINE HAVE_INLINE}
{$ifend}
{$if defined(VER210) or defined(VER220) or defined(VER230) or defined(VER240)
or defined(VER250) or defined(VER260)}
{$define HAVE_RTTI}
{$ifend}
{$if defined(VER230) or defined(VER240) or defined(VER250) or defined(VER260)}
{$define NEED_FORMATSETTINGS}
{$ifend}
{$if defined(FPC) and defined(VER2_6)}
{$define NEED_FORMATSETTINGS}
{$ifend}

Delphi 2007定义了两个VERXX符号 (VER180和VER185)。Delphi 2006和Delphi 2007是二进制兼容的，因此两者均可使用VER180。如果仅需要2007，请使用VER185。
注意： CompilerVersion 最初是随 Delphi 6 引入的，因此较早的版本没有此常量。
