Bug ID: 19029
Summary: _XOPEN_VERSION and _XOPEN_UNIX not defined in XSI
conformance mode
Product: glibc
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: msebor at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
In Section 2.1.4 XSI Conformance, the latest POSIX spec states:
XSI-conforming implementations shall set the symbolic constant _XOPEN_UNIX to a
value other than -1 and shall set the symbolic constant _XOPEN_VERSION to the
value 700.
The following test shows that the latest glibc fails to define either
_XOPEN_VERSION or _XOPEN_UNIX. This problem came up while developing a
portable application that relies on _XOPEN_NAME_MAX, which is also missing
(this is the subject of bug 18229.
#define _XOPEN_SOURCE 700
#include <limits.h>
#define A(expr) _Static_assert (expr, #expr)
A (_XOPEN_UNIX != -1);
A (_XOPEN_VERSION == _XOPEN_SOURCE)
A (_XOPEN_NAME_MAX == 255);
A (_XOPEN_PATH_MAX == 1024);

Move sysdeps/unix/sysv/linux/i386/i486/*.? to i386

sysdeps/unix/sysv/linux/i386/i486/*.? to i386.

--- Comment #1 from Martin Sebor <msebor at redhat dot com> ---
Closing as invalid -- the test case fails to include <unistd.h>. With the
header included as required, the two asserts involving the _XOPEN _UNIX and
_XOPEN_VERSION macros compile successfully (the other two still fail but that's
bug 18229).
