patch about mingwbuild 4.9.1
I think you used the wrong code model: these come from defaulting to the medium-code model intended for x64 Cygwin -- see https://gcc.gnu.org/ml/gcc-patches/2013-03/msg00858.html . Also, please follow the posting guide and do not send HTML: your message arrived rather garbled. I've added a more general way to achieve this in MkRules.dist in R-devel and R-patched.
