sysconf(_SC_ASYNCHRONOUS_IO) != 200112L
Hi!
Newer glibc returns 200809 as a result from sysconf(_SC_ASYNCHRONOUS_IO) (the git commit was done on 26 Feb 2009) and the change seems to be propagated into stable glibc versions (mine is 2.11.2-r3).
The problem is that nearly all aio testcases starts with
if (sysconf(_SC_ASYNCHRONOUS_IO) != 200112L)
return PTS_UNRESOLVED;
So these tests are disabled with newer glibc.
However the changes between posix 200112 and 200908 seems to be minimal (I haven't been able to find the full list of changes, but at least the
testcases seems to work.)
My proposal is to do one of the following:
* remove these two lines to enable the tests
* change them to sysconf(_SC_ASYNCHRONOUS_IO) >= 200112L
(I would gladly prepare patch, once we agree on reasonable solution)

That being said though, it would be nice if we had tests specific to these requirements, in addition to ones that aren't, and if glibc is unnecessarily bumping values then someone needs to talk to Ulrich about not creating unnecessary churn.
The problem is that I've been unable to find a document which sumarizes changes between 1003.1-2002 and 1003.1-2008. And coparing the documentation page by page is troublesome, especially when there seems to be miminal number of changes.
