We need to print a deprecation warning if the user sets a compile flag 
(namely one of those described here: 
http://eigen.tuxfamily.org/dox/Eigen2SupportModes.html) -- even if he 
does not actually use any Eigen2 methods.
Eigen does (or did) use a deprecated attribute for methods where applicable.

Actually, what do we do to produce a warning on all supported systems?
gcc/clang/icc(?) provide #warning, but that's not ISO-C++. I assume for 
MSVC there are some #pragma constructs that should work? Not sure about 
the QCC compiler, but I guess that warning message is not too important 
to bother *g*
