"no success" is far from a good description of your problem.
Anyway:

since you are using lib_LTLIBRARIES, it's .c.lo which is involved here,
not .c.o

Another solution:
Even though you cannot use the right names permanently, you can
use them temporarily.  Try this Makefile.am:

lib_LTLIBRARIES = libadn.la
libadn_la_SOURCES = adn.h adn.c tim.c cyto.c
.c.lo:
.c.cc:
        $(LN_S) $< $@
EXTRA_PROGRAMS = fake
nodist_fake_SOURCES = fake.cc

I tested this, and it works.  The fake program is there to drag in
C++ support.

Please note that though the *.cc files are temporarily created,
make delets them at the end, because they are intermediate.

Could you live with this?

Have a nice day,
