Apparently this the way nested classes are handled in Borland C++ 2007. 
Unless you declare nested classes friends they cannot access the 
containing class's private or protected members.

I have noticed that Borland C++ is not in the list of supported 
compilers. However, I've found that the uBlas library in Boost 1.32 
works for me if I add

    #define BOOST_UBLAS_NO_PROXY_SHORTCUTS

before I include ublas. I haven't done extensive testing, though.

Hope I'll get rid of Borland C++ sooner or later, anyway.

The Boost docs said so, but I was unable to find it on 
http://lists.boost.org. Oops... er... I see it's there now... must have 
been hiding the other day. ;-)

thanks for your help
