[eigen] Documentation build problem

[Helmut Jarausch <jarausch@xxxxxxxxxxxxxxxxxxx>]

Hi,

using today's HG version of Eigen, the html documentation doesn't build  
properly.
E.g. in TopicLinearAlgebraDecompositions.html there is no correct html  
table anymore
like (much) earlier.

I'm using doxygen-1.8.1.

Many thanks for a hint,
Helmut.
