numeric/ublas & gcc 3.0

Hi,

I am using gcc 3.0. Attempt to compile 'test11.cpp'
(with -USE_GCC) results in more than a thousand lines of
error messages and warnings.

Lots of them are caused by missing typenames
in declarations of nested types. 

Furthermore, in exception.h:

../exception.h:28: looser throw specifier for `virtual const char*
   numerics::divide_by_zero::what() const'
/usr/include/g++-v3/exception:56:   overriding `virtual const char*
   std::exception::what() const throw ()'

and similarly for other exception classes.

With all typenames added (3 hours work) and with throw specifiers,
test11.cpp can be compiled. 

But in compilation of test12.cpp and test13.cpp I stumbled upon
an unsurmountable (at least for my knowledge) problem:

/usr/include/g++-v3/bits/stl_iterator.h: In constructor 
   `std::__normal_iterator<_Iterator, _Container>::__normal_iterator(const 
   std::__normal_iterator<_Iter, _Container>&) [with _Iter = const float*, 
   _Iterator = float*, _Container = std::vector<float, std::allocator<float> 
   >]':

A>::iterator1::index1() const [...]'

test12.cpp:127:   instantiated from here
/usr/include/g++-v3/bits/stl_iterator.h:474: cannot convert `const float* 
   const' to `float*' in initialization

(And there were three similar error messages for double*, 
complex<float>* and complex<double>*). 

Sincerely,
