Sorry, Boost.Pool does not currently support MSVC, due to that
compiler's
extreme lack of template support.
I also tried this on the real released VC7.1 (which has been on MSDN 
subscriber downloads for a couple of weeks, now), and, while it 
compiles, I get warnings that point me to some code that looks like 
it's losing precision (size_type reduced to bool) in a calculation.
VC++ has produced that warning for a while now, and it's totally bogus.
Notice that it's a "performance warning" not an "are you sure this is
that you want?" warning, and it's being generated here for *casts* not
implicit conversions.

Another test I tried was a map, actually declared like 
this:
typedef 
std::basic_string t;
std::map > > m;
...and got these errors:

I compiled almost the exact same code:

    #include 
    #include <map>
    #include <utility>

    typedef
std::basic_string
...
...
t;
int main()
    {
        std::map > > m;
    }

with VC++ 7.0 and Boost 1.29, and got no warnings or errors at all.

The command line was:

    cl /D__WIN32__ /EHsc /I"c:\program files\boost" test.cpp

I repeated this with Boost 1.30 and again got no warnings or errors.

I don't have VC++ 7.1 to hand, but I would be surprised if it broke
anything
that worked in 7.0.
