      ChangeLog:        that Jim developped stackovf.c on a 486 running SVR4.0 
(ESIX), and
      ChangeLog:        `boolean'.  This tag conflicts with <sys/types.h> on 
SVR4.

some
      examples/WWW/m4lib/whatis.m4:version, and SVR4, although it has some 
extensions (for example,
      src/stackovf.c:   signal stacks using either SVR4 or BSD interfaces.
      src/stackovf.c:      1. The siginfo parameter (with siginfo.h, i.e., 
SVR4).
      src/stackovf.c:/* SVR4.  */
    
    In particular:

some
    
    Elsewhere in `doc/m4.texinfo', only `Release 3' is referenced:
    
      $ git grep Release 861325a84f231a2a2da307b53ef5ff527d67e876 -- 
doc/m4.texinfo | cut -c 42-
      doc/m4.texinfo:System V, Release 3 version, except for some minor 
differences.
      doc/m4.texinfo:UNIX, such as System V Release 3, Solaris, and 
@acronym{BSD} flavors.
    
    This commit simply changes those last 2 lines by replacing `Release 3'
    with `Release 4'.

commit be2fd0b150a96b8a4835c1b3159ee4349ac40be6
Author: Eric Blake <address@hidden>

    maint: update to latest gnulib
    
    Commit 9f80fa84 picked up a newer regex from gnulib, but at a
    time where the m4 tests rejected glibc regex because it differed
    from gnulib with regards to behavior that POSIX left unspecified.
    
    * gnulib: Update to latest, for regex fixes.
