Write win32-specific code required by the R C-level API.
The rpy2 version in the tip on bitbucket has an attempt at having it...
but I wrote it in a hurry, and without a Windows box to compile it on -
it is most certainly not working, and most likely not even compiling
under win32 (no problem on UNIX-alikes).

I can't tell if the reason is good, but it seemed to me that R's
configure step on win32 does not define R_INTERFACE_PTRS (but I am ready
to hear that I am completely mistaken).

The true reason lies at the C level. Check rpy2/rinterface/rinterface.c
in the source.
