 Thanks for the detailed explanation.
 
 Do you see any chance of making this "sometimes" or "in some cases" more
 specific?
 
 When you say "sometimes", does this mean that when running the same
 scenario 20 times in a row, 3 of them might fail and the other 17 might
 succeed?
 
 When you say "in some cases", does this mean that the behavior is then
 either "always fail" or "always succeed", but no mixture?
 
 Could it have something to do with .PATH, or is it enough to have
 subdir/file?
 
 I ran the following loop for several minutes in the example directory
 that you provided; it always generated consistent output.
 
 make clean
 make > good.out
 while :; do
    make -s clean
    make > new.out
    cmp -s new.out good.out || break
    printf .
 done
 
 Any other ideas to reproduce the wrong behavior?
