23 * Now that configure depends on shell functions, it is possible that
24 configure scripts may fail to run on old platforms that lack a shell
25 with proper function support.
27 * Autotest parallel testsuite support is still a work in progress.
28 There are known issues in job handling under dash and some ksh
29 variants, where a parallel testsuite can hang or cause a 100%
30 processor load. In the current release, the overall autoconf
31 testsuite only exercises parallel autotest under bash and zsh, or if
32 you have defined TEST_PARALLEL_AUTOTEST in the environment.
33 Meanwhile, Cygwin has known problems with named fifos that cause
34 failures when attempting parallel tests in an autotest suite. It is
35 possible that other difficulties will be encountered, whether with
36 shell or platform limitations; help is appreciated in improving
37 parallel testsuite support.
