Hello,

I committed several patches to the boost CVS repository

- unit_vector::find() fix 
- vector_of_vector fix
- compressed_matrix iterator decrement fix
- constructor bypass for std::complex<T> and POD types
- compressed axpy_prod now works with more size_types

I have deferred the serialization patch because I'd like to do some more 
testing and have feedback for the above updates.
