[Message part 1 (text/plain, inline)]

gzip version 1.3.12(Windows) and probaly others too, does not save /
restore file timestamp correctly(Always set to current.
Linux versions, when saving to a local file system, resoter/save correctly,
but if it is a mounted remote filesystem like CIFS in my case, does not.
After a change in the source code that I made,  all Works OK.
The bug is, if copy_stat (&istat) is executed before I close ofd(file
descriptor of a file being saved/restored), those times are not set
properly.
Bu if I put copy_stat after file descriptor(ofd) is closed, and set it ofd
= -1, then, they are all ok

Best regards

1.3.12 is dated 2007 and is pretty old. I'm afraid that we worry only about the 
latest version.

That wouldn't work with the current version, where copy_stat needs ofd to do its 
thing. Can you reproduce the problem with the current version? See:

No further comment in five years, so closing this old bug report.
