Comparisons with other C++11 compilers
There is documentation on the internet for several C++ compilers that lists the C++11 compatibility results for current and past releases. I make no claim to the quality or completeness of the C++11 language compliance for any compilers. I include the links so that you can do your own investigations and comparisons.

C++11 compliance
I am working with our R&D, Q/A and Product Management team to create a document and site where you can explore the C++11 language compliance results based on our testing using the Plum Hall C++ validation suite (stay tuned in January for additional details).
Watch/Download the C++Builder 64-bit Compiler Preview Video
Additional details about the 64-bit C++Builder compiler are available in the preview video. Watch the C++ 64-bit compiler preview video on YouTube at http://www.youtube.com/watch?v=PwwMpBUoR6Y. You can also download the MP4 video file at http://cc.embarcadero.com/item/29197. The preview video is 9 minutes long.
Try the C++Builder 64-bit compiler
The C++Builder XE3 and RAD Studio XE3 free trial downloads have been updated to include the new C++Builder 64-bit compiler. Trial downloads are available at https://downloads.embarcadero.com/free/c_builder
Happy C++mas!
During the first 25 days of December leading up to Christmas, I will blog about the release of the C++Builder 64-bit compiler for Microsoft Windows and C++Builder XE3 support for building VCL and FireMonkey 2 applications.

Vladimir: I just compiled the following statements in a C++Builder VCL application (one TButton) using the C++32-bit compiler in C++Builder XE3 update #1.
int foo()
{
return 11;
}
void __fastcall TForm1::Button1Click(TObject *Sender)
{
auto x = 10;
auto x1 = foo();
auto y = 3.14;
int i=10;
auto a = 1, *b = &i;
Button1->Caption = IntToStr(*b);
}

Takahashi-san: Thank you so much. I just updated the table for Raw string literals. Merry Christmas to you and to all of my friends in Japan.

May be you have different version of the Cbuilder?
I checked many times (XE3 update1) and
auto val = 3.14; always shown me val==3.00
if this has to be 3.14 for Win32 I'll put this issue to the QC. -
Monday, 24 December 2012
And again, auto is the storage class for Builder32, so if we have auto val = 3.14; the default always will be int,
but for the C++11 auto is the auto-typed. -

Vladimir - thanks for the notes. You are right that way back in C++Builder 2009 we added some original C++Ox language extensions - http://docwiki.embarcadero.com/RADStudio/XE3/en/C%2B%2B0x_Features_Index. And since then we have not touched the C++ 32-bit compiler. One of our goals is to someday backport the new C++ 64-bit compiler back to 32-bit Windows - no time frame or firm promise yet - but definitely an aspirational goal.
Sorry for the confusion. -
