Rob,

That's what I thought. But when you wrote:

>>>It's not the ln smarts that are needed, its the cygwin1.dll hard link 
>>>smarts.

I thought you were saying that the special case for copying when a hard 
link is requested on a FAT volume was handled in Cygwin1.dll, not in "ln" 
as I'd assumed.

Randall
