11223	Context does not properly check support for std::integer_sequence	Emile Cormier	olli	"When I build Boost 1.58 with C++11 support on GCC 4.8.2, it fails to build the context library. This is due to the library attempting to use std::index_sequence:

{{{
In file included from libs/context/src/execution_context.cpp:11:0:
./boost/context/execution_context.hpp:202:52: error: ‘std::index_sequence’ has not been declared
}}}

std::index_sequence is a feature only available in C++14.

A workaround would be:
1. First build a C++11-enabled Boost using the --without-context option
2. Build the missing context library using --with-context, making sure that -std=c++11 is NOT added to the cxxflags

My platform is GCC 4.8.2, x86_64-linux-gnu, Linux Mint 17 (based on Ubuntu 14.04)"	Bugs	closed	To Be Determined	context	Boost 1.58.0	Problem	fixed
