10# SYNOPSIS
11#
12# CHECK_GNU_MAKE()
13#
14# DESCRIPTION
15#
16# This macro searches for a GNU version of make. If a match is found, the
17# makefile variable `ifGNUmake' is set to the empty string, otherwise it
18# is set to "#". This is useful for including a special features in a
19# Makefile, which cannot be handled by other versions of make. The
20# variable _cv_gnu_make_command is set to the command to invoke GNU make
21# if it exists, the empty string otherwise.
22#
23# Here is an example of its use:
24#
25# Makefile.in might contain:
26#
27# # A failsafe way of putting a dependency rule into a makefile
28# $(DEPEND):
29# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
30#
31# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
32# @ifGNUmake@ include $(DEPEND)
33# @ifGNUmake@ endif
34#
35# Then configure.in would normally contain:
36#
37# CHECK_GNU_MAKE()
38# AC_OUTPUT(Makefile)
39#
40# Then perhaps to cause gnu make to override any other make, we could do
41# something like this (note that GNU make always looks for GNUmakefile
42# first):
43#
44# if ! test x$_cv_gnu_make_command = x ; then
45# mv Makefile GNUmakefile
46# echo .DEFAULT: > Makefile ;
47# echo \ $_cv_gnu_make_command \$@ >> Makefile;
48# fi
49#
50# Then, if any (well almost any) other make is called, and GNU make also
51# exists, then the other make wraps the GNU make.
