/* As of the first printing of C++ Primer, 5th Edition (July 2012),
|
|
* the Microsoft Complier did not yet support a number of C++ 11 features.
|
|
*
|
|
* The code we distribute contains both normal C++ code and
|
|
* workarounds for missing features. We use a series of CPP variables to
|
|
* determine whether a given features is implemented in a given release
|
|
* of the MS compiler. The base version we used to test the code in the book
|
|
* is Compiler Version 17.00.50522.1 for x86.
|
|
*
|
|
* When new releases are available we will update this file which will
|
|
* #define the features implmented in that release.
