I noticed this from openSUSE just changing this configure option in their 
mingw-w64 cross-compiler package 
(https://build.opensuse.org/package/rdiff/windows:mingw:win64/mingw64-gcc?linkrev=base&rev=73).

Checking cygwin's `x86_64-w64-mingw-g++ -v` (package version 4.9.2-1) gives 
me:

Using built-in specs.
COLLECT_GCC=x86_64-w64-mingw32-g++
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-w64-mingw32/4.9.2/lto-wrapper.exe
Target: x86_64-w64-mingw32
Configured with:
