create and install a subset of config.h in octave-config.h * mk-octave-config-h.sh: New file. * Makefile.am (EXTRA_DIST): Add mk-octave-config.h.sh to the list. (octinclude_HEADERS): Add octave-config.h to the list. (octave-config.h): New rule. * common.mk (do_subst_config_vals, do_subst_cross_config_vals): Don't substitute unused ENABLE options. * configure.ac: Note the reason for using oct-conf-post.in.h. Add OCTAVE_ prefix to ENABLE_BOUNDS_CHECK ENABLE_ATOMIC_REFCOUNT, ENABLE_64, ENABLE_OPENMP, and ENABLE_FLOAT_TRUNCATE in calls to AC_DEFINE. Change all uses. * oct-conf-post.in.h: Define HAVE_OCTAVE_DEPRECATED_ATTR instead of HAVE_ATTR_DEPRECATED. Likewise for HAVE_ATTR_NORETURN and HAVE_ATTR_UNUSED. Change all uses.
