integer.hpp fails to compile with /Za switch

[muckjail@…]

This little snippet complies fine with the /Ze switch which enables Microsoft extensions

#include <boost/integer.hpp> int main(){

return 0;

} But if you disable microsoft extensions with the /Za switch then you get the following errors mess of errors.
