Hopefully this problem is now fixed. Osman, can you test it for me?

The problem is that uBLAS uses std::size_t for compressed matrix index
arrays  by default. std::size_t is a typedef, and on most machines it is
a typedef for unsigned int, but on other machines (typically 64 bit) it
is a typedef for long unsigned int.

I'm now forcing uBLAS to use unsigned int for compressed matrices. With
UMFPACK, problems are then limited to 2GB. In the future, I can change
the default to long unsigned int.

On this point, for portability when using STL, should we be using
std::size_t rather than unsigned int in many places? Would it make sense
to use uint as a typedef to std::size_t rather than unsigned int?
