There is no such restriction for junctions, I just tried it to be safe.

Yes, sorry. I had old NTFS4 information.
NTFS5 supports volume mount points now too.

But shouldn't we check in configure :) for this filesystem then?
(Ha! ntfs5.m4 for MSVC folks)

No, of course not. That would only check the machine where you compile, not
where you install/run.

Tablespaces are not supported on NT4. They throw an error.

So just describe in the docs that only NTFS5 (i.e. W2K and up) supports 
th new tablespace feature.
I could find my cygwin niche then to support it by our native and slow 
symlink implementation :)

I think we are fine.  We have already discussed not even supporting NT4
because tablespaces don't work, but now it will throw a not supported
error, which seems fine.
