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

dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
dnl depending on --{enable,disable}-{shared,static} and on the presence of
dnl AM-DISABLE-SHARED). Otherwise, a static library
dnl $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored.
dnl LIBDIR is used to find the intl libraries. If empty,
dnl the value `$(top_builddir)/intl/' is used.
dnl
dnl The result of the configuration is one of three cases:
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
dnl and used.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 2) GNU gettext has been found in the system's C library.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 3) No internationalization, always use English msgid.
dnl Catalog format: none
dnl Catalog extension: none
dnl The use of .gmo is historical (it was needed to avoid overwriting the
dnl GNU format catalogs when building on a platform with an X/Open gettext),
dnl but we keep it in order not to force irrelevant filename changes on the
dnl maintainers.
