Hi, I noticed that the patchset in Staging for CreateSymbolicLinkW has been
updated.

Just creating this bug to let you know that the simple command from comment #4:
https://bugs.winehq.org/show_bug.cgi?id=44948#c4 doesn`t work anymore.

I have a compiled recent version lying here ( wine-4.3-339-g865d4c3c72
(Staging)). There it seems to wok fine.

The command from comment #4 in one liner:

cd $(mktemp -d) &&
/media/louis/00e587ff-1035-4ec8-8d1f-b69d3527589a/wine-staging4.3/wine64-build/wine
cmd /C "mklink foo bar" && stat foo

000b:fixme:winediag:start_process Wine Staging 4.3 is a testing version
containing experimental patches.

in current Staging 4.7:

cd $(mktemp -d) && /opt/wine-staging/bin/wine cmd /C "mklink foo bar" && stat
foo

Failed to open 'foo'

stat: cannot stat 'foo': No such file or directory

If I remember correctly running Office365 installer with Staging was enough  to
avoid manually copying files to correct locations.
 I did not yet test if that is broken too now in Staging-4.7, will do later
(takes quite some time). Just reporting this simple example for now.
