    It has a name extension of .new because that's what cygwin sets it to.
Cygwin has a limitation that doesn't need to exist. 

Cygwin could rename the old file to file.dll.old, (or if it isn't 
cross-deviced linked,
to "/tmp/file.dll.todelete.001") and move the new file into "file.dll".  
It's an established
behavior of NT. 

Perl had same problem when installing new perl libraries under Windows.  
They moved
to the NT supported method of renaming the old and putting in the new.  
Then you still
setup the file delete after reboot -- but meanwhile, users can use the 
new library,
and programs that have the existing file open continue to operate "fine" 
until they
exit -- then it's the old files that get left around until the next reboot.
