I should know better.  unzip -v gives:

UnZip 5.20 of 30 April 1996, by Info-ZIP.  Maintained by Greg Roelofs. 
Send
bug reports to the authors at Zip-Bugs AT wkuvx1 DOT wku DOT edu; see README for
details.

Latest sources and executables are always in
ftp.uu.net:/pub/archiving/zip, at
least as of date of this release; see "Where" for other ftp and non-ftp
sites.

Compiled with djgpp v2 / gcc 2.7.2.1 for MS-DOS (32-bit) on Apr  1 1997.

UnZip special compilation options:
        ASM_CRC
        COPYRIGHT_CLEAN (PKZIP 0.9x unreducing method not supported)
        USE_EF_UX_TIME

I /think/ that was a version I compiled myself under MSDOS (not Win95),
but I'm not sure.

Aha!  Er, no, not in this version.  Latest is 5.32, just fetched and
compiled (with GCC 2.8.1) and it includes USE_VFAT automatically and
works.  Thanks for the hint...

I expected (naively, I suspect) that the ordinary DJGPP library longame
support would work without doing anything except setting LFN=Y -
presumably UnZip had its own truncation for MSDOS in earlier versions.
