Please submit the changes to fc in a PR to that repo so that it can be integrated into the master branch there and then pulled into this submodule.

In addition, please place the new test cases into their own test module, perhaps test_io_raw.cpp and follow the pattern(s) established in the other test modules so that it is logically easier to find test cases related to certain systems.

You'll need to merge in changes from develop too. Looks like you're using older build scripts that don't install c++ properly and allow it to build on our new base images.

Sure. Would you check EOSIO/fc#99?

@taokayan @b1bart This is so old, I'm presuming that we should start again, rather than keeping this hanging around.
