R devel - Jul 2014 - patch about mingwbuild 4.9.1

recently I used gcc 4.9.1
(http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting
Win64/Personal Builds/mingw-builds/)on windows to build R,but failed when link
R.dll ,it report linker status 5. 
after some digging, I found when use gcc 4.9.1 64 bit on windows there are lots
of .refptr.*(* is r function name) in R.def, which lead build fail.so I add a
simple path to src/gnuwin32/Makefile:

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.
