I'm trying to use sed to trim off all leading "./" patterns from source
filenames in make rules. On an IBM RS6000 the following works as I expected:

   echo 'enquire.o: ./././enquire.c' | sed 's?: \(\./\)\{1,\}?: ?'

yielding

   enquire.o: enquire.c

On our other systems (Sun-4, HP, SGI, and Motorola 68040) it prints
different results. The HP doesn't trim any "./" patterns, while the Sun,
Moto, and SGI all trim one pattern.

Have I incorrectly specified the sed command or are one (or more) of the
vendors' sed implementations incorrect? If so, which one(s)? I'm inclined to
believe the IBM is correct and the others are bugged.

(I suppose this is another argument for perl...)

Thanks,
