Subject: Remove AC_HEADER_SYS_WAIT
X-Git-Tag: 4.12~90
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9e788adf56f4e9952d7223eb14a497645a03f842;p=thirdparty%2Fshadow.git

Remove AC_HEADER_SYS_WAIT

GNU autoconf documentation marks this macro as obsolescent, as
current systems are compatible with POSIX.

Simplify code to unconditionally include <sys/wait.h>, and don't
redefine WIFEXITSTATUS() and WIFEXITED(), since they are mandated
by POSIX.
