[boost] [assign] intel failures in list_of

hi,

I've looked into this now. I don't know where it originally comes from 
(because Intel seems not to print the whole instantiation stack), but 
the 'Array' type in list_of line 157 is const which is of course not 
desirable for the local temporary array.

So, the attached fix *would* fix the problem for intel but it gives no 
answer why there is a const type with this compiler.

Any thoughts?

Stefan
