Subject: * tests/lha-test.in: emulate POSIX shell when it is executed by
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=078c3fc503a5925005b0f5ebdc6e8c3c1811b659;p=lha%2Flha.git

* tests/lha-test.in: emulate POSIX shell when it is executed by
zsh or bash. (this part is derived from GNU Autoconf 2.59)

* tests/Makefile.am: replaced `bash' with `@sh_for_lha_test@'

* configure.ac: search shell programs to execute the lha-test.
