[Glenn Morris]

branch: master
commit 48e384d7104dce8219b169c55a29c9f85024c83f
Author: Glenn Morris <address@hidden>
Commit: Glenn Morris <address@hidden>

    Replace AC_SUBST_FILE in configure with include in Makefiles.
    
    * configure.ac (DEPDIR, MKDEPDIR, deps_frag, lwlib_deps_frag)
    (oldxmenu_deps_frag, lisp_frag): Remove output variables/files.
    (AUTO_DEPEND): New output variable.
    * lwlib/Makefile.in (AUTO_DEPEND): New, set by configure.
    (DEPFLAGS, MKDEPDIR): Set directly via conditional.
    (lwlib_deps_frag): Replace by conditional include.
    * lwlib/autodeps.mk: Remove file.
    * oldXMenu/Makefile.in (AUTO_DEPEND): New, set by configure.
    (DEPFLAGS, MKDEPDIR): Set directly via conditional.
    (oldxmenu_deps_frag): Replace by conditional include.
    * oldXMenu/autodeps.mk: Remove file.
    * src/Makefile.in (AUTO_DEPEND): New, set by configure.
    (DEPFLAGS, MKDEPDIR): Set directly via conditional.
    (lisp_frag): Replace by an include.
    (deps_frag): Replace by conditional include.
    * src/autodeps.mk: Remove file.
