Message-Id: <1404211654-10158-1-git-send-email-ross.burton@intel.com>
Date: Tue, 1 Jul 2014 11:47:34 +0100
From: Ross Burton <ross.burton@...el.com>
To: linux-ext4@...r.kernel.org
Subject: [PATCH] Move e2fsprogs-specific macros from aclocal.m4 to acinclude.m4
Autoconf says that aclocal.m4 is a machine-generated copy of system-wide macros,
whereas acinclude.m4 is for project-specific macros. Reflect this division and
ease building by anyone who needs to re-generate the autotooling by splitting
AX_TLS and CHECK_GNU_MAKE to acinclude.m4.

+# SYNOPSIS
+#
+# CHECK_GNU_MAKE()
+#
+# DESCRIPTION
+#
+# This macro searches for a GNU version of make. If a match is found, the
+# makefile variable `ifGNUmake' is set to the empty string, otherwise it
+# is set to "#". This is useful for including a special features in a
+# Makefile, which cannot be handled by other versions of make. The
+# variable _cv_gnu_make_command is set to the command to invoke GNU make
+# if it exists, the empty string otherwise.
+#
+# Here is an example of its use:
+#
+# Makefile.in might contain:
+#
+# # A failsafe way of putting a dependency rule into a makefile
+# $(DEPEND):
+# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
+#
+# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
+# @ifGNUmake@ include $(DEPEND)
+# @ifGNUmake@ endif
+#
+# Then configure.in would normally contain:
+#
+# CHECK_GNU_MAKE()
+# AC_OUTPUT(Makefile)
+#
+# Then perhaps to cause gnu make to override any other make, we could do
+# something like this (note that GNU make always looks for GNUmakefile
+# first):
+#
+# if ! test x$_cv_gnu_make_command = x ; then
+# mv Makefile GNUmakefile
+# echo .DEFAULT: > Makefile ;
+# echo \ $_cv_gnu_make_command \$@ >> Makefile;
+# fi
+#
+# Then, if any (well almost any) other make is called, and GNU make also
+# exists, then the other make wraps the GNU make.
