    [SV 44742] Fix double-colon rules plus parallel builds.
    
    * remake.c (update_file): Don't update double-colon target status
    if we're still building targets.
    (ftime_t): Don't propagate timestamps for double-colon targets that
    we've not examined yet.
    * tests/scripts/features/double_colon: Add parallel build tests.
    
    Copyright-paperwork-exempt: yes

commit e2ebea35f11059e888b2fe2bfc8b24fda48c1f88

Author: Paul Smith <address@hidden>
Date:   Sun May 1 19:24:20 2016 -0400

    Separate the GNU make load ABI from internal types.
    
    Create an internal type "floc" and convert all users to that type.
    * gnumake.h (gmk_floc): Remove the offset field from this type.
    * loadapi.c (gmk_eval): Convert gmk_floc to internal floc.

commit ba8383efd8b1fded117f2587c78c40b28fe4e016
Author: Paul Eggert <address@hidden>

    Fixes for enhanced GCC warnings.
    
    Move function prototypes into header files and out of .c files.
    Use void argument lists for functions that accept no args.
    Remove unused macros.  Make private functions static.  Align
    types with printf format characters.

commit 6f7fb050b4af7335de259f570b75bf6c217eb1cd
Author: Paul Smith <address@hidden>
Date:   Sun May 1 15:34:42 2016 -0400

    Fix compile issues with Windows and VMS.
    
    * main.c (initialize_stopchar_map): isblank() is not part of C89.
    Install bits for space and tab directly.
    * makeint.h: Don't define vfork; autoconf handles this for us.
    * vmsjobs.c: Rename NEXT_TOKEN to V_NEXT_TOKEN to avoid conflicts.
    * dir.c (print_dir_data_base): Visual Studio C doesn't have int64_t.
    * w32/subproc/sub_proc.c (process_begin): Missing arg to memset().
    * build_w32.bat: Don't use obsolete Visual Studio flags.

    Allow compiling with an ISO C 1989/1990 compiler.
    
    * posixos.c (jobserver_post_child): Use C89 for loop syntax.
    * remake.c (update_goal_chain): Ditto.
    * variable.c (parse_variable_definition): Ditto.
