commit 7044e0c93ca3d52e3e947764e538a0d1f5f2f16a
Author: Paul Smith <psmith@gnu.org>
Date:   Sat Dec 5 16:25:12 2020 -0500

    [SV 59169] Add --debug=why and --debug=print options
    
    Add debug options to print recipes even if they would otherwise be
    silent, and to print the reason that a target was considered out of
    date.
    
    Modify --trace to simply be a shorthand for --debug=print,why.
    
    * NEWS: Announce changes.
    * doc/make.texi (Summary of Options): Document the new options.
    * doc/make.1: Ditto.
    * src/debug.h: Add new flags DB_PRINT and DB_WHY.
    * src/makeint.h: Remove the trace_flag variable.
    * src/job.c (start_job_command): Check debug flags not trace_flag.
    (new_job): Ditto.
    * src/main.c (trace_flag): Make a static variable for switches.
    (decode_debug_flags): Set DB_PRINT and DB_WHY if trace_flag is set.
    * tests/scripts/variables/GNUMAKEFLAGS: Update known-good messages.
    * tests/scripts/variables/MAKEFLAGS: Ditto.

commit 94d90776914f4086e2402a0a6a9dfa3d1a9a7d0c
Author: Paul Smith <psmith@gnu.org>

    * configure.ac: [SV 58836] Copy build.sh to the build directory

commit c4cc2e95953baae800eb9c694c691f7263317035
Author: Paul Smith <psmith@gnu.org>

    [SV 57676] Support included files being built after failing
    
    If a -include file does not exist, then some subsequent operation
    creates it, then allow it to be successfully included.
    
    * src/read.c (eval_makefile): If our last mtime was NONEXISTENT then
    reset it to 0 so we'll check it again.
    * tests/scripts/features/include: Add a test for this behavior.
