I'm inclined to believe the IBM is incorrect and most of the others are
correct. Your sed should be trying to match ONE pattern of the form
": ./"[blah]  and it does(on most machines) and replaces it. What you
want is for it to match multiple "./"s after the ": ", so try
    echo 'enquire.o: ./././enquire.c' | sed 's?: [\./]*?: ?'

Could be.
