Commit message was not enough ? $ac_snip2 contains NL. And in order to print it, `print -r --' command is used on mksh. BTW, printing without double-quoting, NL in $ac_snip2 is replaced with a space. Because of this, M4 does not return contents expected. As a result, test for $ac_snip2 fails. -- KO Myung-Hun Korean OS/2 User Community : https://www.os2.kr/
