Hi Ralf,

almost certainly this has to do with the rounding/truncation of sub-second
timestamps, possibly handled in a different way by Autotools and GNU Make
3.81.

2.65 as required for the ObjC++ patch.

To fit into my infrastructure I did:
 cd test
 make TESTS='aclocal9.test' check
but that should be equivalent.

The third attempt failed; the files you asked for are attached, together
with the output from "ls -lrt --fu aclocal9.dir".

In case you need more info please let me know.

Peter
