Standard placement operator

[Sergey Grekhov]

Hello, Daniel!
Thanks for your answer!

My interest about STL containers has quite simple prerequisite. As far 
as I know Genode implementations of data structure (particularly, 
Avl_tree) has some issues and Genodelabs does not recommend it for usage 
in user applications. The reasons that issues are still not resolved is 
quite serious: Genode is kept as simple as possible. So, I was thinking 
about making a kind of porting of STL to Genode. But, it seems that this 
work is redundant since it is possible to use containers by means of 
specifying stdcxx in makefile. The only trouble is using Genode 
allocators/new operator instead of native C++ ones.

I have this only in mind and even did not start to do anything. =)

Kind regards,
Sergey.
