  Ok, then try to disable all the feature with:

./configure --disable-default-maxevents --disable-aio-signal
--disable-lio-signal --disable-lio-wait --disable-cancel-fd
--disable-buffered-aio

  that way, the configure script will not try to autodetect
kernel features.

  The configure options available may be found with

    configure --help

  aio_read and aio_write with no event notification should work
provided you implemented the ARM syscall wrappers.

  Sebastien.
