Hi,

On cygwin, the following program

#include <iostream>
#include <boost/filesystem.hpp>
int main() {
  auto p = boost::filesystem::path{"foo"};
  p /= "bar";
  std::cout << p.string() << '\n';
  return 0;
}

outputs:
foo\bar

but cygwin is a posix system and I expect:
foo/bar

I read in the doc that "User-defined BOOST_POSIX_API and
BOOST_WINDOWS_API macros are no longer supported."

So how can I have posix support on cygwin?

Thanks,

Frédéric
