Generally use c++11 features

[csoeger]

Should we start using the "new" c++11 features?

Thinks that might be usefuI:

• auto
• for_each, ...
• constexpr
• static_assert
• initializer lists

I think it is a good idea.

Most of the mentioned features are included in the most common compiler for several years now, so I think it is no problem to use them. Only the constexpr support does not seem to be widespread, we should not use it for now.

List of supported features for different compilers and when it was introduced:
gcc https://gcc.gnu.org/projects/cxx0x.html
clang http://clang.llvm.org/cxx_status.html
intel https://software.intel.com/en-us/articles/c0x-features-supported-by-intel-c-compiler

We now use the following features witch work with the following compiler versions (according to their web pages)

• long long (gcc 4.3, clang 2.9, icc 11.1)
• static_assert (gcc 4.3, clang 2.9, icc 11.1)
• auto (gcc 4.4, clang 2.9, icc 12.0)
• std::execption_ptr (gcc 4.4, clang 2.9, icc 12.0)

We really want to use the std::exception_ptr, so our minimal requirements are:
gcc 4.4
clang 2.9
icc 12.0
We should try to keep it to this requirements for now.
