>Description:
	Autoconf tools could be used with pipe. For example,
        fresh autopoint from gettext uses autom4te this way:

         http://git.savannah.gnu.org/cgit/gettext.git/commit/gettext-tools/misc/autopoint.in?id=eea2dddde35037d25b3f240ab95836b6adeaf517

        As the wrapper currently eats stdin, autopoint doesn't work. It
        causes problems bootstrapping projects, e.g. I got this error
        with libvirt:

       (22:54) novel at dev:~/code/libvirt[master] %> ./autogen.sh
	I am going to run ./configure with no arguments - if you wish
	to pass any to it, please specify them on the ./autogen.sh command line.
	running bootstrap...
	./bootstrap: Bootstrapping from checked-out libvirt sources...
	./bootstrap: consider installing git-merge-changelog from gnulib
	./bootstrap: getting gnulib files...
	./bootstrap: autopoint --force
	autopoint: *** Missing version: please specify in configure.ac through a line 'AM_GNU_GETTEXT_VERSION(x.yy.zz)' the gettext version the package is using
	autopoint: *** Stop.
	Failed to bootstrap, please investigate.

	Attached patch fixes problem for me.
