[Emacs-diffs] master 10444dc: Generate nt/gnulib.mk from lib/gnulib.mk


From: Eli Zaretskii
Subject: [Emacs-diffs] master 10444dc: Generate nt/gnulib.mk from lib/gnulib.mk
Date: Tue, 3 Jan 2017 15:48:43 +0000 (UTC)

branch: master
commit 10444dcf77711bf3360f865fcb0d446a83e1bfb5
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>

    Generate nt/gnulib.mk from lib/gnulib.mk
    
    This was proposed by Paul Eggert <address@hidden>,
    with the purpose of avoiding manual maintenance of
    nt/gnulib.mk.
    
    * nt/gnulib-modules-to-delete.cfg: New file.
    * nt/Makefile.in (AM_V_GEN, am__v_GEN_, am__v_GEN_0)
    (am__v_GEN_1): New variables.
    (${srcdir}/gnulib.mk): Rules to generate gnulib.mk from
    lib/gnulib.mk and list of modules in gnulib-modules-to-delete.cfg.
    
    * make-dist (nt): Add gnulib-modules-to-delete.cfg to the list of
    files to link.
    * configure.ac (GNULIB_MK): Compute the value according to $opsys.
    * autogen.sh: Create nt/gnulib.mk if it doesn't exist, before
    running autoreconf.
    * Makefile.in (gnulib_mk): New variable.
    ($(srcdir)/nt/gnulib.mk): Rule to produce it.
    (AUTOMAKE_INPUTS): Use $(gnulib_mk) instead of a literal file
    name.
    * .gitignore: Add nt/gnulib.mk.
    
    * src/w32.c (acl_errno_valid): Implement it here, as we no longer
    build the acl-permissions module from Gnulib.
