When Cygwin 2.10 is released, then GCC will need to be rebuilt without the latter. If you wish to test _FORTIFY_SOURCE with the current snapshot, then just move /usr/lib/gcc/$arch-pc-cygwin/6.4.0/include/ssp out of the way. Note, however, that any binaries so built will require a snapshot DLL at runtime, and will not run on the 2.9 DLL.
