libstdc++: Define _GNU_SOURCE for secure_getenv on Cygwin [PR107511]
As in r12-6867-ge20486d508afdf we need to define _GNU_SOURCE explicitly for Cygwin, because configure finds it in libc but it isn't declared unless we request it. libstdc++-v3/ChangeLog: PR libstdc++/107511 * libsupc++/eh_alloc.cc (_GNU_SOURCE): Define.
