Subject: [PATCH] speedo: Enable additional runtime protections on Windows.

* build-aux/speedo.mk (speedo_w32_cflags): Remove -mms-bitfields
because it is for a long time the gcc default.  Enable control flow
protection.
--

Note that due to mingw static linking problems with libssp the stack
protector is not yet enabled.
