The following reply was made to PR bin/14509; it has been noted by GNATS. From: Ruslan Ermilov <ru@ucb.crimea.ua> To: Archie Cobbs <archie@whistle.com> Cc: FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: bin/14509: bug in make(1) Date: Mon, 25 Oct 1999 11:15:31 +0300 Hi! It turns out to be a sh(1) bug: $ sh -e -c 'test "yes" = "no" && :; echo OK'; echo $? OK 0 $ sh -e -c ':; test "yes" = "no" && :; echo OK'; echo $? 1 Here is what sh(1) manpage says about `-e' option: : :-e errexit : If not interactive, exit immediately if any untested command : fails. The exit status of a command is considered to be explicitly : tested if the command is used to control an if, elif, while, : or until; or if the command is the left hand operand of an ``&&'' : or ``||'' operator.
