bug in bdist_wininst cross compile?

has anyone had any success with cross compilation and bdist_wininst; I have 
modified build_ext very slightly to fix a small bug in cross compilation related 
to library order. That seems to fix

setup.py build --plat-name=win-amd64


however, when I try to do a clean build of an exe ie

rm -rf build

setup.py bdist_wininst --plat-name=win-amd64

it appears as though build is invoked with the wrong plat-name ie I see this in 
the output

> running bdist_wininst
> running build
> running build_py
> creating build
> creating build\lib.win32-2.6
> creating build\lib.win32-2.6\reportlab
> copying src\reportlab\rl_config.py -> build\lib.win32-2.6\reportlab
......
> C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\cl.exe /c /nolog

followed by errors related to a missing library (the amd64 version won't work 
with a win32 build).

If I build first with

setup.py build --plat-name=win-amd64

and then use

setup.py bdist_wininst --plat-name=win-amd64 --skip-build

then I seem to get a proper amd64 exe.

I think the problem can be fixed by modifying distutils/command/bdist_wininst.py 
using this patch

which forces bdist_wininst's version of the plat_name forward onto both build 
and bdist.
