despair86 bdc54835c2 initial windows server port. Requires Windows 2000 Server or later.
- updated CMake build script
- builds with Microsoft C++ 19.1x. such builds require Windows 8.1 or later
  unless you have the .NET Server 2003-toolset (v141_xp)
- windows port requires a C++17 compiler since cpp17::filesystem is POSIX-only
- HAVE_CXX17_FILESYSTEM manual toggle in CMake. You must manually specify where
  std::[experimental::]filesystem is defined in LDFLAGS or CMAKE_x_LINKER_FLAGS.
- IPv6 support can be added at any time, and the windows sdk still has that
  inline getaddrinfo(3) if it can't find a suitable IPv6 stack.
- inline code for mingw-w64: there's a few bits and pieces still missing simply because
  mingw-w64 derives its windows sdk from wine and reactos, and then writing all the newer
  stuff into it by hand straight from the MSDN manpages.
- misc. C++11 stuff (nullptr and friends)
- Internal file handling code takes UTF-8 or plain 8-bit text, NTFS is UTF-16, so
  std::filesystem::path::c_str() is wchar_t. That's no good unless you first
  call std::filesystem::path::string().
- implemented getifaddrs(3) and if_nametoindex(3) on top of GetAdapters[Info|Addresses](2).
- updated readme with new info

BONUS: may implement Solaris/illumos IOCP someday...
