Is there any chance that we can try to allow full use of the c++11 
standard on all supported platforms?
Note that c++1 includes language changes  as well as standard c++ 
library changes.

You have as the supported platforms:

I will make a wild guess and say that only vxWorks should cause a 
problem for complete support for c++11.

I also have a question about how current vxWorks implementations 
implement new.
Do current implementations have a good way to handle the heap?
In the past the implementation caused severe memory fragmentation, which 
could be a show stopper for using the c++ standard library.

What about RTEMS?
