proposed patch

When using one of the CopyFile functions, the destination file is arbitrarily
set to read-only. This occurs due to an uninitialized read introduced in the
kernel32-CopyFileEx patch. The attribute is set depending on an uninitialized
bit.

This bug was likely accidentally introduced in the rebase
eedc72d581e5de3e87cd21519f3b5767a35b8b2c.

Expected behavior: the attribute should be set depending on the attribute of
the source file.

See the attached patch for my proposed fix.
