[eigen] exception specifications...

[Hauke Heibel <hauke.heibel@xxxxxxxxxxxxxx>]

Hi,

After reading that the C++ committee decided to deprecate exception
specs and after reading

a) http://www.gotw.ca/publications/mill22.htm

and

b) http://www.boost.org/development/requirements.html#Exception-specification

I thought it might be a good idea to remove the throw() declarations
we are still having in our code. As a matter of fact, I belong to one
of the users who assumed compiler optimizations given these
declarations but "trial and error" has already taught me that this
assumption was not quite correct.

Any objections about removing those declarations?
