[Cbc] multithreaded cbc for windows

We are in a similar situation to Petru's. In our case, we are building
our own executable against the binaries provided by the CoinBinary project
(whose mailing list I am CCing, since it isn't clear whose bailiwick this
is).
When building Cbc from source, the command "./configure" should be
replaced with "./configure -C --enable-cbc-parallel" in order to enable
multithreading. We can make this work on Linux but have been stymied on
Windows (building under MinGW).
Multithreading with Cbc on Windows is a high priority for us.

[Cbc] multithreaded cbc for windows
Sorry if this question has already been answered.
I would need a multithreaded version of cbc.exe for Windows.
The installable cbc does not seem to allow parallel stuff ("-threads" is
reported as "No match"). For building a multithread-enabled version
with VS (2010), it seems that the symbol "CBC_THREAD" must be
defined. If I define the symbol, I get a very serious message saying that
a
header file is missing: pthread.h.
It seems that I'm stuck, so I bother you with this question:
Can I get / build a multithreaded version of cbc.exe for Windows?
If I need to build one, what symbols or C++ / link configuration options I
must use? If some external headers are necessary, where can I get them?
Petru
