Actually, the reference implementation does symlink/copy all DLLs from
the same directory as the python binary or a DLLs/ subdirectory, and
also any executable beginning with "python", which would include
pythonw.exe.

We should certainly update the PEP with more detail about how things
look different on Windows, currently it's pretty much describing the
POSIX behavior (my fault; Vinay's done all the Windows work and I'm not
as familiar with it).
