a quick look shows that the current install-sh indeed contains this
race condition.  You are probably right that we should fix this and
review current GNU mkdir before we enhace the documentation to
encourage people to use "$(mkdir_p) -m MODE"

But I don't think this is a blocker for Paul's patch.
All my complaints were considered, and we have Alexandre's approval,
so I guess you could check it in.

Have a nice day,
