I think (but I am not windows expert) this hints at a 32 bit / 64 bit mismatch.

It stumped me too today. I didn't have too much time for this but here is
quick run-down

  i)    I think RInside_0.2.7.zip as shipped for Windows is in fact deficient
        in the sense that it should have, but doesn't have, a static library
	for 64 bit use.

  ii)   So I rebuilt RInside_0.2.7 locally from the .tar.gz, opting for 
        the --no-multiarch flag to ensure I get a 64 bit build.

  iii)  I then noticed that using Makefile.win results in an incomplete /
        wrong call for libRinside.a.  As a stop-gap measure, I fixed this via
           RINSIDELIBS=../../lib/x64/libRInside.a

  iv)   With those changes / fixes, 'make -f Makefile.win' works and results
        in working executables.  I didn't have to copy any dlls into the
        working directory.

I hope to make some time over the next few weeks to address i) and iii).
Help from experienced Windows users would certainly be appreciated :)
