Sorry, you lose. They were all re-writes, essentially top to bottom.
Only (some of) the module names remain.


I think the older manufacturers are more likely to fix their loaders if
they can first sell an "ANSI standard C compiler" using the current loader.
When customers start complaining that the brain damaged loader doesn't
let them bring in programs from other systems, they might actually fix it.

On the other hand, the manufacturers would also be quite happy NOT to have
an ANSI standard C (if this would require re-writing the loader). Then no one
buys it, and it never gets fixed.

Sort of two "vicious" circles... which one you get depends on whether the
initial compiler can be called "standard-conforming".

Perhaps the standard should require minimum 6 char caseless externals,
but the implementation of anything less than arbitrary length case-distinct
is, as they say, 'deprecated'

P.S. The Random House College Dictionary defines:
dep-re-cate: v.t. 1. To express earnest disapproval of.
   2. To protest against (a scheme, purpose, etc.).
   3. to depreciate or belittle.
   4. (archaic) to pray for deliverance from.
[ From the latin, deprecat(us), "prayed against, warded off" ]

I often find the 4th definition appropriate :-)
