Yes.  We rejected environment-variable-based xlog location for reasons
that apply equally well to Windows.  The xlog location *must* be stored
in a physical file in the data directory; anything else is too unsafe.
The current technology for that is a symlink.

While it doesn't have to be a symlink as opposed to some sort of config
file, I don't have the slightest problem with saying that we don't
support relocation of xlog on older Windoid platforms.
