Have you tested it? This will not work as HAVE_LIBAIO_H is in include/config.h,
thus only for C. For Makefile it must be done via autotools (search for AC_SUBST
in m4/). I thought TST_TEST_TCONF usage, but you're right, that problematic
source is part of libcontrollers.a (i.e. part of a library, not normal C
binary).


Kind regards,
Petr
