I don't think that --with-sysroot is here the problem.
The implementation in pex-win32 for win32_spawn seems to be ok for
XP64, but for 64-bit native toolchain on Vista64 there seems to be a
problem. I'll try to investigate further what the problem really is.
On Vista64 the CreateProcess seems to fail.
