Patch Level: 0
Release Status: release

Description:
        "make check" reported some discrepancies which boil down to
        the fact that the tests assume that the environment variable
        "b" is not set.

Repeat-By:
        $ cd bash # the Bash source directory
        $ export b=/net/knick/home/eggert/bin
        $ make check

Fix:

2001-05-02  Paul Eggert  <eggert@twinsun.com>

        * tests/arith.tests, tests/array.tests: Don't assume that "b" is unset
        as it might have been set in the environment.
