Subject: Remove configure's wait3 test as we don't care about the rusage.
X-Git-Tag: OPENLDAP_SLAPD_BACK_LDAP~712
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=4863d98084d150cef8a8cd4a3094576fdfebe641;p=openldap

Remove configure's wait3 test as we don't care about the rusage.
Rewrite all child waits to use wait4 (for consistency only).
