- 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... -despair86
