I'm guessing this might be solvable by updating to a newer version of

I'm building with Visual Studio 2019 and I get a whole bunch of errors
simply by adding this line to an empty source file:-
#include "boost/rational.hpp"
It seems to be the same 6 errors but at various different lines - i.e.
these errors, over & over again:-

error C2086: 'int __m128': redefinition
I just wondered if this might ring a bell with someone? e.g. might
there be some preprocesser #define that I should've defined? (or a
#define that I shouldn't be defining...)
Thanks for any suggestions, John
#include "boost/rational.hpp"
int main()
{
return 0;
}
The above code compiled against VS2019 gives no errors.
