[darcs-users] darcs patch: Resolve issue1173: support hard links on NTFS.

[Eric Kow]

Hi Dmitry,

Do you think you could have a look at this?

You (and Salvatore) may want to pay attention to this thread:
  http://lists.osuosl.org/pipermail/darcs-devel/2006-December/005162.html

But since Salvatore didn't modify maybe_relink.c, we should be safe :-)

Hooray!

If this works, it means Windows users get to benefit from the shared
patch cache.  Then again, it also means they will run into the
timestamps issue.  I assume we think the tradeoff is still worth it.

Nobody complained the last time I asked in 2006-12:
