Cygwin specific:

Install the gcc-g++ package (if you have multiple choices for gcc, install the
same version as the core compiler) and the corresponding libstdc++6 and
libstdc++6-devel packages.
(unless you've already done that - try cygcheck -c -d).

Generic GCC usage:

To compile C++ executables, use g++ to compile (not gcc) so that the front-end
looks for the proper headers and libraries. It is also advisable to call the C++
source files .cc or .cxx rather than .c (using .c makes the front-end believe
you want to compile C, not C++).
