RE: how to use not "also" symbolic link time, but "only"

>Your question is not very clear (to me).

I just want a way to correctly write a rule for a make target, that is a soft 
symlink.  It seems to me there is currently no way to do that.  If I (as I 
should) depend on the Makefile, then the target will always rebuild, which is 
not correct.  

>Obviously you can "touch" the target file ("from")

Of course not I can't :)   A file such as "from" is typically a 
version-controlled file, which is read-only, unless I need to change something, 
which I clearly don't, then I can check it out and edit it.  Cannot just go 
around the filesystem and touch source files because I want to.  

What I do want, is for make to create me a symlink, and I want to do it 
"correctly" by make standards, that means, rebuild the symlink only when 
necessary - when the name of the target changes (change to Makefile), or when 
the symlink does not exist.  

It seems to me this is a natural thing to do, and it seems to me there is no 
way to do it?
