As far as I can see that works for cc65 and ca65 - but not ld65.

With ld65 I cannot see an option that makes it forget its compiled paths 
- or did I miss anything ?

If I understand you correct:
This requires every developer to be aware of this "feature" - and 
plaster his makefiles with options compensating for the current search 
path approach - if not his project will not work properly in situations 
that I described in the initial email.

It sounds wrong to me that every developer should compensate for this 
feature in his makefiles. And we all know that this will not happen. I 
bet that almost every (lets say 99 of 100) CC65 based open-source 
projects found on the internet will have problems building out of the 
box on systems like yours and mine. Changing the search path priorities 
would solve this problem as far as I can see.

Is there any compelling reason for not changing the search path priority 
as suggested ? It sounds to me that this feature would ease up your own 
development and shorten your makefiles considerably ;-)
As far as I can see there is no real compatibility problem if the env 
vars is not setup - I guess the user did that on purpose. And if unset 
everything works as allways - which I would believe is the most usual 

Kind regards Uffe Jakobsen
