Bug ID: 56925
           Summary: msys2-64/cygwin64: unlink of read-only file fails
           Product: Wine
           Version: 9.12
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wineserver

A few notes and backtraces in wine and cygwin.
In another attempt to check the state of msys2 or cygwin I found following
issue trying to update a msys2-64 installation:
# LANG=C pacman -Suy
   :: Synchronizing package databases...
   ...
   warning: could not remove lock file /var/lib/pacman/db.lck
   error: failed to init transaction (unable to lock database)
   error: could not lock database: File exists
   ...
A simpler version to reproduce is this:
  rm -f test.txt
  LANG=C wine cmd
    echo test > test.txt
    attrib +r test.txt
    c:\msys64\usr\bin\rm.exe -f -v test.txt
Returns:
  /usr/bin/rm: cannot remove 'test.txt': Permission denied
This tests were done with a wine tree including patches for this bugs:
