Good question, we have a few different situations here:

* The compiler vendor (Intel in this case).
* Some other compiler they may be emulating (GCC or MSVC in Intel's case).
* The compiler front-end used (EDG in this case).
* The compiler back-end used (Intel in this case).

A similar situation occurs with IBM's new Intel compiler, which uses the 
clang front-end but isn't really clang (it has some features clang 
doesn't have, some regular clang features are unimplemented, and the 
usual llvm back-end has been replaced by IBM's as far as I know).

So given that there is no EDG compiler as such, and since we're 
certainly not emulating EDG, I would vote for something like 
BOOST_FRONTEND_EDG (or some similar variation).

Not sure if this helps, John.
