Thierry, I have just uploaded a (patched) test version here:
http://ourcomments.org/Emacs/DL/EmacsW32/test/
I think that the patches does not affect the problem we have been
working with here.
Lennart, I confirm that the version I uploaded from your site do not
solve the uid issue.
That's because Jason installed his fix only on the release branch, not
on the trunk.
Any other test I could do to make things progress ?
Could you please try the latest trunk? This problem is supposed to be
fixed there, along with a similar problem with inode numbers.
TIA
