eliminate code duplication in oct-conf-post.in.h and octave-config.h * oct-conf-post-private.in.h, oct-conf-post-public.in.h: New files, split form oct-conf-post.in.h. * Makefile.am (libgnu/libgnu.la): Depend on oct-conf-post-public.h and oct-conf-post-private.h instead of oct-conf-post.h. (BUILT_SOURCES): Update. (nodist_octinclude_HEADERS): Add oct-conf-post-public.h to the list. * build-aux/module.mk (GEN_CONFIG_INC): Replace oct-conf-post.h with oct-conf-post-private.h and oct-conf-post-public.h. * configure.ac: Replace code using oct-conf-post.h with equivalent actions for oct-conf-post-private.h and oct-conf-post-public.h. * mk-octave-config-h.sh: Instead of generating code that is also duplicated in oct-conf-post.h, include the file oct-conf-post-public.h that is also included in Octave's config.h file.
