Does 'ar' work with native MS Windows libs?

[Coatimundi]

I need to break open a library I created with Visual Studio and insert 
some objects also compiled with Visual Studio.

Will Cygwin's ar command work for this task?

Alternatively, is there a Windows tool better suited to this?
Maybe there's even something that ships with Visual Studio, but I 
wouldn't expect an answer to that question here.

Thanks for indulging these newbie questions.  I'm used to working with 
Linux and am leaning heavily on Cygwin as I start to do some Windows 
development.

Thanks!
