- Naaww... I already read the documentation. Niko is indeed wrong, "-)"
- is used to disable the DPMI, not "-(". The option "-(" is used exactly
- as a workaround the famous '486 bug - they are saying so in the docs.
- So, what did PKWare spend one year for???? To invent the option "-("
- as a solution of that bug? To introduce half a dozen -really- serious
- bugs (unlike the '486 bug which is not that serious and is not their
- fault, after all)? Just recall those people that used to say "ah, yes,
- PKWare indeed wants to produce a really good product, that's why they
- don't want to release it. When they release it, it'll be a killer." A
- killer, yes. For other people's data... :-((
