Re: [ublas] compilation error using prod()

Patrick, Paul, and anyone else!

I have been thinking about this a bit further.

At the moment we have several major compilers still interpreting the prod 
overloads differently. Also to me it looks like compiler implementing DR214 
will never choose the prod<temp_type> overload as unambigeous.

I think the solution in uBLAS must be to drop these overloads and remove them 
from the documentation. The "temp_type(prod(" form is a suitable alternative.

I still think the currect GCC 4.0.1 is odd as overloads defined with a simple 
template argument (say S) behave differently then those defined with 
expression<E>. This may be worth persuing as a bug report but I suspect given 
the history of DR214 this may be a long and hard process!

All the best,

Michael
