[Rd] Does dlltools in 64-bit rtools for windows support 64-bit machine type?

Hi,
I've been trying to get the python bridge (rpy2) to build for 64-bit R
and python. The current stumbling block is that mingw can't use the
python27.lib file that comes with CPython and so I need to generate
libpython27.a.
When I use dlltool from rtools to do that however, I end up with a 32-bit file:
>"G:\Rtools\gcc-4.6.3\i686-w64-mingw32\bin\dlltool" -e libpython27.a -d python27.def python27.dll
>objdump -f libpython27.a
libpython27.a: file format pe-i386
More problematically, x86_64 is not listed as supported by objdump:
Usage G:\Rtools\gcc-4.6.3\i686-w64-mingw32\bin\dlltool <option(s)>
<object-file(s)>
-m --machine <machine> Create as DLL for <machine>. [default: i386]
possible <machine>: arm[_interwork], i386,
mcore[-elf]{-le|-be}, ppc, thumb
Am I doing it wrong?
Regards,
Johan
