commit 144f436c4b7b4aac49817193b9490b1f1d358e7b
Author: Paul Smith <psmith@gnu.org>
Date:   Mon Mar 15 01:15:18 2021 -0400

    * tests/scripts/features/exec: Small cleanup

commit 52056d7b2cb5c3c889096d2138b5b19124cdf6b0
Author: Paul Smith <psmith@gnu.org>
Date:   Mon Mar 15 01:09:32 2021 -0400

    Ensure variable_buffer is always set.
    
    Initialize the global variable_buffer in main() so that it is never
    a null pointer.  Then invoking variable_expand("") is never needed:
    simply use the variable_buffer pointer when we want to restart the
    variable buffer.  The main point of this simplification is not to
    keep a separate pointer to the beginning of the buffer: this is
    dangerous because the buffer may be re-allocated.  Instead always
    use the variable_buffer pointer itself.
    
    * src/variable.h (initialize_variable_output): Publish.
    * src/expand.c (initialize_variable_output): Remove static.
    * src/main.c (main): Initialize variable_buffer.
    * src/file.c (enter_prereqs): Don't call variable_expand("") and
    don't save a separate buffer pointer than might be outdated.
    (expand_deps): Ditto.
    * src/read.c (record_files): Ditto.
    * src/remake.c (library_search): Ditto.

    [SV 59881] Handle vertical TAB consistently
    
    While parsing makefiles get_next_mword() was treating VTAB as a word
    character rather than a word separator.  However, when using
    find_next_token(), for example in patsubst_expand_pat(), we treated
    VTAB as a word separator causing multiple words to appear where we
    didn't expect them.
    
    * src/makeint.h (END_OF_TOKEN): Change from a loop to a boolean check.
    * src/misc.c (end_of_token): Move the loop here.
    * src/read.c (get_next_mword): Skip whitespace, not just blank, to
    find the start of the word and use END_OF_TOKEN() to decide when the
    current word is finished.

Date:   Sun Mar 14 16:32:47 2021 -0400

    [SV 59870] define/undefine prerequisites are not target-specific vars
    
    * src/read.c (parse_var_assignment): If called in a target-specific
    variable context don't allow define/undefine as variable assignments.
    * test/scripts/variables/define: Add a test.
    * test/scripts/variables/undefine: Add a test.
