No, it does not. *Some* features work, but gcc 13.1 was the first
release where everything mandated by C++17 is working, or at least
compiling.
So far g++ in Cygwin 3.5.3 cannot compile anything in std::pmr:*, e.g.
std::pmr::monotonic_buffer_resource, std::pmr::polymorphic_allocator,
std::pmr::string, ruling out any realistic C++17 apps (of course,
HelloWorld will work).
