Even with set -u, the && should have short-circuit semantics, so you shouldn't ever test any variable which hasn't been set before, if you order the tests in the right way. > It would be a _lot_ of work to support set -u. Actually, I have used it from time to time for debugging purposes, but more for the libtool script.
