Nope.  -k mungs the filenames to 8.3 format and fakes the "OS made by"
byte to indicate DOS FAT.  I'm not sure if it affects EAs or not.  In
general PKUNZIP doesn't mind long filenames, but it will barf if the
file has multiple dots in it, I think.

No, EAs are ignored, except when you use PKZIP to update an archive (in
which case it will destroy *all* of the EAs).

...and you'll keep your long filenames under Win95 VFAT or NT's NTFS.
