You are right 2 times. Yes, InfoZip unzip supports LFNs, and yes,
unzip386.exe doesnot support LFNs. Unzip386.exe is an very old, msc/dj
v1.1 compiled version of unzip 5.12.
If you compile infozips unzip with djgpp v2, you will have LFN-support.
Check http://www.cdrom.com/pub/infozip/ for a ready made dos (DJGPP
v2.01 compiled) executable, inside a self-extracting-exe.

For an installer this might or might not be very useful, because this
unzip needs cwsdpmi.exe under plain DOS, which is probably in the zip
to be installed. But if your installer needs dpmi services, you
already have the same problem.

I once (3 months ago) had compiled unzip with pmode/DJ as stub, but
this executable didn't run under certain conditions (IIRC it was
because it needed emm386.exe in config.sys not to contain NOVCPI,
which I had, and many more people might have, so end of that story for
me.)
