If it helps, after installing the nuwen distro and the latest version
of Rtools (for tar), both the release R-3.1.2 and R-patched (see )
builds stop on Windows7 64bit with the error below, probably related
to what Hin-Tak Leung said earlier. I can't even get to the point to
see if compat.c will fail.
windres -F pe-x86-64 -i dllversion.rc -o dllversion.o
