Using gcc-mingw-4.5.0 C++0x

After

> cd libs/test/build
> bjam toolset=gcc cxxflags="-std=c++0x"

I get the following compile error

Given that you're using experimental complication mode, this is not a showstopper for 1.45. Anyway, how about providing a patch?

Replying to vladimir_prus:

I have moved to lightweight_test so for me this is no more a show-stopper. I have no time now to provide a pact.

You do not need to compile boost.test library itself in std=c++0x mode. Compiler removes extensions and sticks to ansi. You can use std=gnu++0x though.
