[eigen] Does c++ use of "norm" bother anyone else?

[Mark Borgerding <mark@xxxxxxxxxxxxxx>]

According to matlab/octave and 
http://en.wikipedia.org/wiki/Norm_(mathematics)
  norm(3+4j) =  abs(3+4j) == 5

but in C++:
 norm( complex<float>(3,4) ) == 25
 abs( complex<float>(3,4) ) == 5


Just thought I'd mention it while we are thinking about problems to 
solve with Eigen::Complex.
