This isn't a cygwin problem.  When you build a C++ program, you either
have to use the C++-aware version of gcc (g++) or manually specify
-lstdc++ on the command line to link the C++ libraries.

If you are looking with explorer, yes.  The first has /bin mounted
over it and the second is intentionally empty.
