Fixed the Microsoft problem.

Now compiles and runs.

Are you sure that you're not missing a #include?
It works for me.

#include 
#include <vector>

int main() {
  std::vector<int> x = { 3, 1, 4 };
  boost::sort::parallel_stable_sort( x.begin() , x.end() );
}

I presume that if I replace the or with something belonging to an earlier standard that this may get me a bit further.
`or` was a keyword in C++98 (See [lex.digraph]).  Try
compiling with /permissive-
