This actually seems to work rather well - I've committed a fix to 
develop, but the new code is only enabled for Intel-15 and later as 
that's all I have installed at present.

I've enabled SFINAE-expression support + binary literal support under 
MSVC as these seem to be working well there, and SFINAE-expression 
support enables a lot of very useful code.

Linux GCC emulation I've left alone, even though there do appear to be 
several features supported beyond what the underlying GCC version 
supports.  The compiler also seems to be ignoring -std= flags and just 
supporting everything always?
