c++.stl - map in a namespace

Greetings,

I have encountered the following problem:
using the stl version that is on the CD, whenever a map object is declared
within a namespace, the compiler gives two strange errors in stl_map.h
This is a short sample that exposes the problem, along with the exact compiler
output:

#include <map>

namespace MyNameSpace
{
map<int,int> M;
}

void main()
{
}


Compiler output:

sc Test.cpp -p -mn -C -WA -S -3 -a8 -c -gf -D_CONSOLE=1 -Ic:\dm\stl -oTest.obj 
Error: c:\dm\stl\stl_map.h(232): '?8' is already defined
Error: c:\dm\stl\stl_map.h(234): '?M' is already defined
Lines Processed: 5536  Errors: 2  Warnings: 0
Build failed

Is there currently any workaround for this short of keeping maps outside
namespaces?

Thanks,
Dimitri

Thanks.
Also I have found another similar problem: when exception support is enabled,
you can't declare string variables within a namespace.
