The MS-Windows code uses regular files while the GNUish code
uses symbolic links. Suppose one instance of Emacs is running
on a GNUish host while the other one is running on MS-Windows,
and they are both accessing the same file via NFS. Won't
that cause problems? The MS-Windows code will use a regular
file .#FOO while the GNUish code is programmed to ignore locking
for FOO if a regular file .#FOO exists (for compatibility with
non-Emacs programs that use .#FOO for other purposes).
Also, suppose an MS-Windows Emacs uses .#FOO as a lock file while
a non-Emacs program uses .#FOO as a regular file for something else.
Won't there be problems of a different sort?
