Subject: AIX 7.1 defines O_CLOEXEC but it can't be used outside the kernel.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=da98428e91ae95386a4a79da553675fb2b623615;p=sudo

AIX 7.1 defines O_CLOEXEC but it can't be used outside the kernel.
Redefine O_CLOEXEC if it doesn't fit in an int and pipe2() is missing.
