[Cbc] Compiling on Windows

[Wenchel, Seth]

I have a 24-core server on which I'd like to run Cbc 2.6.  It needs to run
windows because of some other projects so I can't change it.

I've tried building Cbc using both the Cbc.sln inside MSVS 2k8 (v9) and
under cygwin using gcc4.  I haven't included any of the 3rd party files.
C/C++ isn't my strong suit so if these errors are really common, I
apologize.  If I can get this figured out I'll happily contribute notes
and/or files back to the project.  As a side note, I've successfully built
Cbc on my Mac using the online instructions.

MSVS
After updating the include directories for the Osi* files, I was able to get
everything to build but had the following linking error.

./configure ends with the correct message as noted but make fails.  I've
only included the last portion of the output, but send the rest if needed.

Sooner or later any problem will get big enough that you can¹t solve it.
But it¹s nicer if you make it later.
