It's not torture. :-) And it's been around since 1989 (history).

Actually, I'm fairly certain even 3.4.4 (or similar) would've been good enough for me. But 2.95.3 was the last of its branch, and something increased the size a lot after that. I wasn't willing to sacrifice the stable 2.03p2 library or some auxiliary tools (make, rm, cwsdpmi, wmemu387) just to fit a slightly bigger compiler.

It's not a "run from floppy" version, it just fits compressed on a single 1.44 MB (not overformatted) floppy. The idea is to make migration between machines easier, to have a small but good ANSI C compiler (32-bit, POSIX, LFN). It only needs 6 MB of space (or 3.5 if UPX'd), which is good for hard disks or even RAM disks. And I finally got it to pack with .7z, so you don't need a bunch of RAM to decompress anymore either (tested unpacking successfully on my 486 Sx/25 w/ 8 MB of RAM without swapping). I consider this the spiritual successor of EZ-GCC for v1 (which was quickly outdated) even if not exactly meant to be a 1-to-1 mirror (no G++, no GDB, no GRX).
