[boost] [1.36][ublas] VC8/SP1 with ADL problem?

Hi!

Posting to devel, since I believe sucking ADL may be the cause ...
I have a headache problem with VC8/SP1 which leads to some questions.

1. Can you confirm this behaviour?
2. Do you have a quick fix workaround for this?
3. Can this be fixed in future versions of boost

The following innocent looking piece of code (boiled down within 2 days -sigh)

---snip---
#include <boost/numeric/interval.hpp>
#include <boost/numeric/ublas/traits.hpp>

#include <boost/numeric/ublas/vector.hpp>

namespace ublas = boost::numeric::ublas;

void trigger_ublas_compile_error()
{ 
        ublas::vector<double> boom = ublas::zero_vector<double>(5);
}
---EOF---

compiled with VC8 SP1 in DEBUG mode with a command line similar to
(some private include paths ripped off)

/Od /I "PATH_TO\boost_1_36_beta"  /D "WIN32" /D "_WINDOWS" /D "_DEBUG" 
/D "_CRT_SECURE_NO_WARNINGS" /D "_SCL_SECURE_NO_WARNINGS" 
/D "BOOST_PYTHON_STATIC_LIB" /D "_MBCS" /Gm /EHsc /RTC1 /MTd 
/Fo"Debug\\" /Fd"Debug\vc80.pdb" /W3 /nologo /c /ZI /TP 
/errorReport:prompt  /bigobj

bails out with

Ugly as it is: it will compile in any release mode, be it static or dynamic 
linkage :-(
