[boost] [config/interprocess] visual C++ express og /Za option

I got this error when I switch on the /Za option:

d:\boost\trunk\boost\interprocess\detail\workaround.hpp(20) : fatal 
error C1083: Cannot open include file: 'unistd.h': No such file or directory

The only thing I did was to add /Za to my Jamroot. The compiler switch 
is supposed to turn of microsoft extensions. Does anyone have any clues 
to what is going on?

Thanks
