[pgpool-hackers: 665] Serious problem with automake

[Tatsuo Ishii]

Hi Usama,

We seem to have serious problem with autoconf configuration.  I'm
going to fix them as soon as possible. Before going further, we need
to agree on which version of those tools should be used. Autotools
behavior is changed depending on its version, and we need to fix the
version if want stable developping environment.

In my case I mainly use following versions provided by Ubuntu 14.04.

autoconf: 2.69
autoheader: 2.69
automake: 1.14.1

What about you?

automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled.  For now, the corresponding output
automake: object file(s) will be placed in the top-level directory.  However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
