I've made another attempt (thanks to some very good hints from Rod P. on news://comp.os.msdos.djgpp). But I also kept the older .ZIP just in case I made it worse somehow.

http://ftp.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/file/7zip/9.20.1/p7z9201b-testing.zip

So this one should (hopefully) work with DOS-style backslashes '\'. My brief tests indicate no obvious errors (besides a few minor nits). So 7zr, 7za, 7zcon all apparently work correctly (though I hate that the sfx is default extract instead of test or list, ugh): "copy /b 7zcon.exe + blah.7z blah.exe" (though 7zdecode.exe is smaller!).

= nit #1). Updating still tries using LFN-only blah.7z.tmp, which is annoying in SFN. I'm too tired right now to fix that (not that I know where it is exactly either). Workaround: "ren blah.7z blah", "7za d -r blah. sources\*.c", "ren blah *.7z".

= nit #2). Previous build was crashing with -mx8 and -mx9 when compressing .EXEs. I blindly assumed it was a compiler bug uncovered in BCJ*.cpp, so I rebuilt those BCJ*.o (only) with -Os (instead of -O2), and now it works fine.

= nit #3). Doesn't recognize BLAH.7Z [sic], but blah.7z is accepted fine. Dunno.

Unpack it and/or use 32LITE. Or nag the vendors. (Maybe turning off heuristics helps??) Annoyingly unavoidable problem.

You mean without HX? Yes, HX + 7ZA.EXE still works. Pretty cool alternative.
