+# 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.
