From f2466c319fee707e6c753c1311dd15367f04793b Mon Sep 17 00:00:00 2001 From: "Haelwenn (lanodan) Monnier" Date: Fri, 24 May 2024 08:38:44 +0200 Subject: [PATCH] m4: Only expose what GNU gettext also exposes Otherwise gettext-tiny m4 libs ends up overriding other versions of vendored gnulib, making autoreconf fail. Additionally I checked that each m4 file has it's required automake functions, which can be listed with the following command: $ grep AC_REQUIRE m4/*.m4 | grep AM --- m4/ansi-c++.m4 | 128 --------------- m4/codeset.m4 | 24 --- m4/configheader.m4 | 1 - m4/fcntl-o.m4 | 134 ---------------- m4/glibc2.m4 | 31 ---- m4/glibc21.m4 | 34 ---- m4/intdiv0.m4 | 87 ---------- m4/intldir.m4 | 19 --- m4/intmax.m4 | 36 ----- m4/inttypes-pri.m4 | 42 ----- m4/inttypes_h.m4 | 29 ---- m4/lcmessage.m4 | 35 ---- m4/lock.m4 | 47 ------ m4/longlong.m4 | 113 ------------- m4/printf-posix.m4 | 48 ------ m4/size_max.m4 | 79 --------- m4/stdint_h.m4 | 27 ---- m4/threadlib.m4 | 391 --------------------------------------------- m4/uintmax_t.m4 | 30 ---- m4/visibility.m4 | 77 --------- m4/wchar_t.m4 | 24 --- m4/wint_t.m4 | 74 --------- m4/xsize.m4 | 12 -- 23 files changed, 1522 deletions(-) delete mode 100644 m4/ansi-c++.m4 delete mode 100644 m4/codeset.m4 delete mode 100644 m4/configheader.m4 delete mode 100644 m4/fcntl-o.m4 delete mode 100644 m4/glibc2.m4 delete mode 100644 m4/glibc21.m4 delete mode 100644 m4/intdiv0.m4 delete mode 100644 m4/intldir.m4 delete mode 100644 m4/intmax.m4 delete mode 100644 m4/inttypes-pri.m4 delete mode 100644 m4/inttypes_h.m4 delete mode 100644 m4/lcmessage.m4 delete mode 100644 m4/lock.m4 delete mode 100644 m4/longlong.m4 delete mode 100644 m4/printf-posix.m4 delete mode 100644 m4/size_max.m4 delete mode 100644 m4/stdint_h.m4 delete mode 100644 m4/threadlib.m4 delete mode 100644 m4/uintmax_t.m4 delete mode 100644 m4/visibility.m4 delete mode 100644 m4/wchar_t.m4 delete mode 100644 m4/wint_t.m4 delete mode 100644 m4/xsize.m4 diff --git a/m4/ansi-c++.m4 b/m4/ansi-c++.m4 deleted file mode 100644 index c299860..0000000 --- a/m4/ansi-c++.m4 +++ /dev/null @@ -1,128 +0,0 @@ -# ansi-c++.m4 serial 9 -dnl Copyright (C) 2002-2003, 2005, 2010-2017 Free Software Foundation, Inc. -dnl This file is free software; the Free Software Foundation -dnl gives unlimited permission to copy and/or distribute it, -dnl with or without modifications, as long as this notice is preserved. - -dnl From Bruno Haible. - -# Sets CXX_CHOICE to 'yes' or 'no', depending on the preferred use of C++. -# The default is 'yes'.
