Subject: bug#72267: automake 1.17 issue with new AM_SILENT_RULES
Date: Tue, 23 Jul 2024 19:23:44 +0200

I use homebrew on macOS Sonoma 14.5. This package system
installed the version 1.17 automake (I use a binary package
but the source one refers to this metadata:
  desc "Tool for generating GNU Standards-compliant Makefiles"
  homepage "https://www.gnu.org/software/automake/"
  url "https://ftp.gnu.org/gnu/automake/automake-1.17.tar.xz"
  mirror "https://ftpmirror.gnu.org/automake/automake-1.17.tar.xz"
  sha256 "8920c1fc411e13b90bf704ef9db6f29d540e76d232cb3b2c9f4dc4cc599bd990"
  license "GPL-2.0-or-later"

My problem is simple: configure generated by autoreconf includes
this line:
AM_DEFAULT_VERBOSITY=0ac_config_headers="$ac_config_headers config.h"

i.e. the last macro generating AM_DEFAULT_VERBOSITY setting
misses to add a newline after its expansion.

I can propose an easy patch which fixes the problem for me:
at the end of the silent.m4 file (m4 directory in sources
but installed at another location my homebrew add a newline
in the AM_SILENT_RULES macro setting AM_DEFAULT_VERBOSITY:
