- Where did you get the idea that dead code elimination was an exclusive
- 'feature' of Turbo Pascal? There are other compiler products that
- have been doing it for longer than TP without using TPU's. TPU's may be
- a more convenient vehicle for accomplishing it, but the point is
- moot, since Borland has achieved the same thing with BC++ as well,
- without the use of TPU's. I would suspect the reason Borland doesn't
- change, is that they recycle vast amounts of compiler code between
- successive versions of their product, and that this code is heavily
- dependant on interacting with TPU's and not with .OBJ's. Another
- consideration might be Borland's "Fastest Compiler" claim to fame and
- marketing gimick, the proprietary TPU format undoubtedly gives them a
- speed boost.
