+64-bit MinGW Build on Cygwin
+----------------------------
+
+  cd {build_directory}
+  CC=/usr/bin/x86_64-w64-mingw32-gcc CXX=/usr/bin/x86_64-w64-mingw32-g++ \
+    cmake -G"Unix Makefiles" -DCMAKE_AR=/usr/bin/x86_64-w64-mingw32-ar \
+    -DCMAKE_RANLIB=/usr/bin/x86_64-w64-mingw32-ranlib {source_directory}
+  make
+
+This produces a 64-bit build of libjpeg-turbo that does not depend on
+cygwin1.dll or other Cygwin DLL's.  The mingw64-x86_64-gcc-core and
+mingw64-x86_64-gcc-g++ packages (and their dependencies) must be installed.

+
+32-bit MinGW Build on Cygwin
+----------------------------
+
+  cd {build_directory}
+  CC=/usr/bin/i686-w64-mingw32-gcc CXX=/usr/bin/i686-w64-mingw32-g++ \

+MinGW-w64 Build on Windows
+--------------------------
+
+This produces a 64-bit build of libjpeg-turbo using the "native" MinGW-w64
+toolchain (which is faster than the Cygwin version):
+
+  cd {build_directory}
+  CC={mingw-w64_binary_path}/x86_64-w64-mingw32-gcc \
+    CXX={mingw-w64_binary_path}/x86_64-w64-mingw32-g++ \
+    cmake -G"MSYS Makefiles" \
+    -DCMAKE_AR={mingw-w64_binary_path}/x86_64-w64-mingw32-ar \
