But there is no AIX 7.1 bug. If fstatat would return wrong st_size fields,
the return code would have been 3, not 1. Kevin Brott reported an exit code
of 1, which means, he saved the file as "foo.c", not "fstat-test.c", as was
intended.
$ gcc -Wall fstat-test.c 
$ ./a.out 
$ echo $?
0

The test that you put into openat.m4 succeeds (return code 0) on AIX 7.1
for me.
$ gcc -Wall foo.c
$ ./a.out 
$ echo $?
1
$ echo xxx >conftest.file
$ ./a.out 
$ echo $?
0

So I think the entire patch is a workaround against a nonexistent bug.
(And if it was a real bug, it would have had to be documented in
doc/posix-functions/fstatat.texi.)
