Summary: Threads not detected in mingw build

Initial Comment:
Using boost on Windows 2000 with the mingw compiler. 
Compiling like this works fine:
bjam -sTOOLS=mingw

I copy the threaded release-dlls to a relevant place and 
start using Boost.Thread. My code (which uses 
Boost.Thread) works fine on Linux. When compiling with 
mingw, I get a lot of lines like this:

In file included from headers/Position.h:10, from 
main.cpp:7:
C:/boost/boost/thread/thread.hpp:17:5: #error Thread 
support is unavailable!

Tested with Boost 1.30.2 and latest CVS as of December 
9 2003.

If I compile with
-DBOOST_HAS_THREADS
and
-DBOOST_HAS_WINTHREADS

Then I get some warnings about the above constants 
being redefined, but things work fine.

I believe that mingw is not recognized as a platform 
supporting native win32 threads, which is an error, as 
far as I know.

By the way: I tried running "configure" with 
BOOST_HAS_WINTHREADS=1 as described on 
http://boost.org/libs/config/config.htm#configuring but 
that didn't help.
