there was no talk about this. Somebody previously suggested using hard links on NTFS,
if available, but that did not lead anywhere.

I think the primary concern is that while the filesystem might support hard or soft links
now, existing programs do not, and presumably, if somebody's backup -- or another other --
program chokes on Boost, user will blame us. However, I don't use Windows enough to be
able to decide. I'm happy to implement whatever the concensus here might be.
