I've been doing some trial and error with /NODEFAULTLIB as suggest by MS 
with not a vast amount of sucess.

I build using a makefile. If I exclude libcmt.lib I get the new and delete 
problems shown above.

If I exclude nafxcwd.lib several of my objects have an unresolved external 
of __afxForceEXCLUDE

My suspicion is moving away from boost and toward the Cypress USB library. 
I didn't expect device drivers to use MFC.

If I explicitly include nafxcwd.lib in my library list, it links 
sucessfully. :-(
