Thanks Gael.

Regarding PermutationMatrix, there is a warning caused by
is_convertible_impl template struct due to an int being converted to
bool and causing warning C4800 (forcing value to bool 'true' or 'false'
(performance warning) at Eigen/src/Core/util/Meta.h:101). I had to dig
through the huge stack of diagnostics to locate the problem source.
