I think that is the best way to accomplish this. GNU tar does
something similar except they are a bit more explicit. E.g.
gtar: gcc-8.3.0/include: Cannot mkdir: Permission denied
You might consider:
syswarn(1, errno, "Unable to mkdir %s", name);
instead so it is clear exactly what is failing.
Either way, OK millert@
