FPC: 7-Zip or UPX ; TC++ pros and cons (Miscellaneous)

First of all, switching to 7-Zip has been vaguely discussed here before (by Steve and marcov), but it wasn't considered realistic due to potential platform issues, portability concerns, lack of testing, as well as no Pascal srcs for such (unlike Zip).

Secondly, they could stop using UPX, esp. if they all hate UPX so much, but it would increase download size ... although UPX's best uses LZMA anyways, so switching to 7-Zip would offset that.

(As for UPX license conflict, I don't know of any, but using UPX-UCL can easily fix that, which is 100% same compression for LZMA, only very vaguely worse ratio for UCL instead of closed-src NRV.)

Here's what I recently packaged for FreeDOS (if anybody here cares, highly doubt it):

Eh? No, I think they only stopped bothering to SFN-ize the srcs. Otherwise, everything still works. (Besides, 2.04 beta is from 2003, so that's "only" five years, heh.)

Nor C++0x, boo hoo.

One of the only full ANSI C freeware ones I know of. All the others are only subsets, thus not as good.

It is if you want to compile from x86-64 without DOSEMU. Or if you wanted to target other OSes, which are becoming more common every day.

To be honest, even GCC has imperfect C99 support. And most people don't want or use it anyways (ahem, MSVC).

AFAICT, even 286 is not really supported, only 186. I dunno, it's still good, just less than optimal (e.g. OpenWatcom produces faster code).

You mean the compiler overall? Blame 386+ opcodes or (heh) use UPX. ;-)

What's unique? It works with TC++, even virtual memory. Not enough? ;-)
