Hardlinks don't work on FAT filesystems since FAT doesn't support them.
Up to Cygwin 1.7.0-60, hardlinks on FAT were faked by copying the file.
This has obvious downsides (unsecure, potential denial-of-service
problems, portability), so we discussed and decided to remove this fake
and to return an error instead when trying to create a hardlink on a FAT
FS: http://cygwin.com/ml/cygwin/2009-09/msg00208.html

Which is bad since FAT32 has no security at all.  Any process of any
user on the machine can overwrite any file, even in the Windows folder.
NTFS is much more secure and has a couple of features you never get with
FAT32, and hardlinks are only one minor advantage.  You should really
update the filesystem to NTFS using the on-board convert.exe tool.

As for X, it should have a fallback method if the /tmp filesystem
doesn't support hardlinks.
