m4-1.4.10 breaking autoconf?

[Thomas Klausner]

Hi!

After the m4 update in pkgsrc there have been reports of breakage in
packages where autoconf is run. In pkgsrc this affects e.g. mng,
firefox, thunderbird and others.

In the case of mng, the output looks like this:
# /bin/rm -f configure.in && /bin/ln -sf makefiles/configure.in .; /bin/rm -f 
Makefile.am && /bin/ln -sf makefiles/Makefile.am .; aclocal; 
/usr/pkg/bin/libtoolize --automake; automake -a --foreign -i; autoconf
configure.in:9: installing `./missing'
configure.in:9: installing `./install-sh'
# ./configure
#

That's the complete(!) configure output.

I'll attach the generated configure script.

Used software:
autoconf-2.61
automake-1.10
libtool-1.5.22
mng-1.0.10 as test case
(all from pkgsrc)

You can get the mng distfile from http://libmng.sf.net/ or
http://prdownloads.sourceforge.net/libmng/libmng-1.0.10.tar.gz?download

Any ideas?
 Thomas
