I have merge this Branch into the current CVS HEAD. This is the only way I can
test it on a couple of new compilers. In particular I am hopefull that the
changes will get the HP compilers working. They were rejecting the
initialised references, which is understandable.

If this works the next release of uBLAS should cover all modern compilers
other then SunPRO.

I encourage everyone to test the CVS HEAD if they can. It brings together all
the fixes introduced over the last month.
