as mentioned, it makes no differences

both origin and destination are outside on cygwin tree.

	Dear all, please disregard this thread. 
	It was a false alarm because I did not have unzip installed under Cygwin64 
	and its shell found some stray unzip from Dell utilities in Windows path.
	Sorry for disturbing you without grounds.

works fine for me on any relative or absolute destination

Cygwin64, 'unzip -d' misbehaviour vs. Cygwin32

[Wladimir Mutel]

	Dear all,

	I have a .zip archive on a different NTFS filesystem than Cygwin64 TMP
	folder (say, .zip on I: and TMP on C:). I create a temporary folder
	by 'mktemp -d' and then try to unpack .zip archive into that folder :
	unzip -d $folder $archive
	I notice that files are unpacked into I:\TMP\ folder instead of
	C:\Cygwin64\tmp\ (unzip recreates temporary subfolder with same name
	inside I:\TMP\, while initial subfolder under c:\cygwin64\tmp\
	remains empty)
	Trying to work around this problem, I do this :
	p=$(pwd)/$archive # archive is relative path under /cygdrive/i/ ,
                           # so I construct abs.path
	( cd $folder
	  unzip $p ) # in subshell to keep current pwd unchanged
         Then I get a message like :
unzip:  cannot find either /cygdrive/i/path/archive.zip or 
/cygdrive/i/path/archive.zip.zip.

	Even more, unzip -v /cygdrive/i/path/archive.zip invariably fails in this way 
under Cygwin64. What I see is that unzip accepts only relative paths for archive 
files. And that it improperly handles specified unpack directory (-d).

	No such problems are observable under Cygwin32. unzip works exactly as 
specified with both absolute and relative paths, as well as with unpack folder 
on different filesystem from .zip archive.

	Please try to reproduce my findings and fix them on Cygwin64 side
	or tell me how could I fix them myself (if it is my personal problem).

	Thanks in advance for your help.
