Yes, I got discouraged and I'm too busy with other things to keep wasting time
on this and getting stuck in an endless patch submission loop.

This part is broken:
+        if(!(dwAttr & setAttr))
+            SetFileAttributesW(path, dwAttr | setAttr);
+        if(dwAttr & clrAttr)
+            SetFileAttributesW(path, dwAttr & ~clrAttr);

And Alexandre states he would like to check if the file exists first and
display an error message if it isn't, though this is redundant as FindFirstFile
returns ERROR_FILE_NOT_FOUND if the file is not found and adding a separate
check is wasteful, and I'm not sure the Windows version provides an error, I
can't check as I removed Windoze from my machines. Anyone else is free to
finish this.
