I don't know really, but I am feeling that Pelle has other priorities right now. I wish him luck and health and a long happy life.
In the past he must have invested a considerable amount - perhaps too much - of his given lifetime in all those assemblers, compilers and tools. The "community" - whatever virtual entity this is - must be very very thankful to him for sharing the fruits of his work. From my own experience it probably must have been perhaps not only working days "from 8 to 5" but long nights and weeks full of mental struggling.
But enough of that "romanticism". I read that PellesC is an improved lcc. Obviously to prevent PellecC to go down the sink, and to make it open source, license matters must be clarified with Fraser/Hanson, and perhaps with other Pelles' contracting companies.
I am just hitting the bush here, of course, but I would deeply regret it, if in 10 years from now this wonderful C compiler, IDE and assembler would only be nostalgia.
