[eigen] Feeback to Rev #914777. (pre RC1)

[FMDSPAM <fmdspam@xxxxxxxxx>]

Hi Benoit,

I'm sorry for my poor English. It is surly the lack of eloquence what 
let my mails appear a little bit harsh. I'm really thankful for all your 
efforts.

OK, that said: My compiler is not able to finish.
Can please confirm someone else the current code in regard to MSVC 2008 
(express Edition)?

Should it be enough to rebuild /build resp.) the solution with MSVC, 
once created by Cmake or have I to recreate the entire solution with 
Cmake everytime I update my working copy to be sure ?

Problems found by my MSVC are:

a) there is a flood of warnings (all out of one source)
"
warning C4717: 
'Eigen::ei_dot_novec_unroller<Eigen::CwiseBinaryOp<Eigen::ei_scalar_difference_op<double>,Eigen::Matrix<double,4,1,2,4,1>,Eigen::Matrix<double,4,1,2,4,1> 
>,Eigen::Matrix<double,4,1,2,4,1>,4,0>::run' : recursive on all control 
paths, function will cause runtime stack overflow
"

b) some warning of this kind:
...\..\test\geometry.cpp(98) : warning C4244: '=' : conversion from 
'double' to 'float', possible loss of data
       ..\..\test\geometry.cpp(421) : see reference to function 
template instantiation 'void geometry<float>(void)' being compiled
...\..\test\geometry.cpp(112) : warning C4305: 'argument' : truncation

from 'double' to 'float'
...\..\test\geometry.cpp(244) : warning C4305: '=' : truncation from 
'double' to 'float'

c) finally two error occur:

compiler.
