We cannot call MinGW a fully supported platform for C++11 yet:
- Concurrency is not yet supported by MinGW, so it is disabled by default
- A problem in the memory model / library loader is preventing derived type
casts from working. This may be able to be worked around, but has not been
yet.
- ChaiScript no longer includes or automatically instantiates std lib
- ChaiScript constructor now requires an std lib instance in the form
of a ModulePtr object
- This new layout facilitates better usage of compilation firewalls and
factories for reducing the overall impact of ChaiScript on a project
