1763 | dnl which cannot be handled by other versions of make. The variable |
1764 | dnl _cv_gnu_make_command is set to the command to invoke GNU make if it exists, | |
1765 | dnl the empty string otherwise. | |
1766 | dnl | |
1767 | dnl Here is an example of its use: | |
1768 | dnl | |
1769 | dnl Makefile.in might contain: | |
1770 | dnl | |
1771 | dnl # A failsafe way of putting a dependency rule into a makefile | |
1772 | dnl $(DEPEND): | |
1773 | dnl $(CC) -MM $(srcdir)/*.c > $(DEPEND) | |
1774 | dnl | |
1775 | dnl @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND))) | |
1776 | dnl @ifGNUmake@ include $(DEPEND) | |
1777 | dnl @ifGNUmake@ endif | |
1778 | dnl | |
1779 | dnl Then configure.in would normally contain: | |
1780 | dnl | |
1781 | dnl CHECK_GNU_MAKE() | |
1782 | dnl AC_OUTPUT(Makefile) | |
1783 | dnl | |
1784 | dnl Then perhaps to cause gnu make to override any other make, we could do | |
1785 | dnl something like this (note that GNU make always looks for GNUmakefile first): | |
1786 | dnl | |
1787 | dnl if ! test x$_cv_gnu_make_command = x ; then | |
1788 | dnl mv Makefile GNUmakefile | |
1789 | dnl echo .DEFAULT: > Makefile ; | |
1790 | dnl echo \ $_cv_gnu_make_command \$@ >> Makefile; | |
1791 | dnl fi | |
1792 | dnl | |
1793 | dnl Then, if any (well almost any) other make is called, and GNU make also | |
1794 | dnl exists, then the other make wraps the GNU make. | |
