commit 3fc99a48e14b3f61d7103d93eb7159f3b980a086
Author: Paul Smith <address@hidden>

    * maintMakefile: Add a rule for storing preprocessor output.

commit 87a5f98d248fe63fe6e3e53ee3e1b1b1fa5e49dc

    [SV 102] Don't show unnecessary include file errors.
    
    Delay the generation of error messages for included files until we
    are sure that we can't rebuild that included file.
    * dep.h (struct dep): Don't reuse "changed"; make a separate field
    to keep "flags".  Get rid of dontcare and use the flag.
    (struct goaldep): Create a new structure for goal prereqs
    that tracks an errno value and the floc where the include happened.
    Rework the structures to ensure they are supersets as expected.
    In maintainer mode with GCC, use inline to get type checking.
    * read.c (eval_makefile): Return a struct goaldep for the new
    makefile.  Ensure errno is set properly to denote a failure.
    (read_all_makefiles): Switch to goaldep and check errno.
    (eval): Don't show included file errors; instead remember them.
    * remake.c (update_goal_chain): Set global variables to the current
    goaldep we're building, and the entire chain.
    (show_goal_error): Check if the current failure is a consequence
    of building an included makefile and if so print an error.
    (complain): Call show_goal_error() on rule failure.
    * job.c (child_error): Call show_goal_error() on child error.
    * main.c (main): Switch from struct dep to goaldep.
    * misc.c (free_dep_chain): Not used; make into a macro.
    * tests/scripts/features/include: Update and include new tests.
    * tests/scripts/options/dash-B, tests/scripts/options/dash-W,
    tests/scripts/options/print-directory,
    tests/scripts/variables/MAKE_RESTARTS: Update known-good-output.

    * job.c (child_error): Add filename length to output length.
