uiop:delete-directory-tree fails on Win CCL

[Wimpie Nortje]

On CCL windows uiop:delete-directory-tree gives an error when the tree contains read-only files. Examples are git *.idx and *.pack files.

The reason is that CCL uses _wunlink() to delete the files and that fails with error -13 Permission denied.

The docstring for uiop:delete-directory-tree says
"Delete a directory including all its recursive contents, aka rm -rf."

To make the "rm -rf" functionality consistent, uiop needs to delete such trees on Windows without throwing errors.

How would you do that on WinCCL ?

[Wimpie Nortje (wnortje)]

I am using Windows command "attrib -r -h tree-root /s /d" just before
delete-directory-tree as a workaround.

WinCCL supports #_chmod but I don't know if that is the correct
function. I will post again if I find a better solution.
