using c++0x threads with the win32 threading model

[Heiko Harders <heiko dot harders at gmail dot com>]

Hello,

I am on a quest to use g++ in MinGW 64 running in a Windows environment. 
I'm especially interested in the c++0x threads because it allows 
standard cross-platform multi-threading.

Unfortunately I didn't get this to work (using a very recent Mingw-w64 
snapshot that uses gcc 4.5.0). I did some research and I think I found 
out why. Perhaps somebody on this list could confirm this and/or answer 
some of the questions I have about the win32 threading model.

First of all, the c++0x threads don't seem to work because in the 
`thread' header file the file `<bits/gthr.h>' is included, which 
includes in turn some threading model specific files (like 
`<bits/gthr_posix.h>'). While the header `<bits/gthr_win32.h>' does 
exist, it is not included from `<bits/gthr.h>'. The comments in 
`<bits/gthr.h>' further mention support for several threading models, 
but the win32 threading model is not amongst these. Am I looking in the 
right direction for reasons why the c++0x threads do not work with the 
win32 threading model?

If the above is correct: is support for win32 c++0x threads being worked 
on at the moment? If that is the case, any indication when it will be in 
a usable state? What must be undertaken to implement this support?

I hope somebody can give me some insight in these questions.

Regards,
Heiko
