Subject: [PATCH 1/4] Fix warnings related to subdir-objects

Use AM_INIT_AUTOMAKE in configure.ac to define options such as
subdir-objects, instead of AUTOMAKE_OPTIONS in Makefile.am, as it
allows to avoid warnings during autoreconf:

examples/Makefile.am:25: warning: source file '../lib/connect.c' is in a subdirectory,
examples/Makefile.am:25: but option 'subdir-objects' is disabled
