Autotools are failing on the head...

[Sam Roberts]

auto-* versions (I'm running debian/testing):

autoreconf (GNU Autoconf) 2.54
autoconf (GNU Autoconf) 2.54
autoheader (GNU Autoconf) 2.54
automake (GNU automake) 1.4-p6
libtoolize (GNU libtool) 1.4.2a
aclocal (GNU automake) 1.4-p6

With the trunk autogen.sh I get:

address@hidden:~/p/mailutils/trunk$ sh autogen.sh
autoreconf: `aclocal.m4' is updated
configure.ac:35: warning: AC_PROG_LEX invoked multiple times
autoreconf: `aclocal.m4' is unchanged
configure.ac:35: warning: AC_PROG_LEX invoked multiple times
configure.ac:35: warning: AC_PROG_LEX invoked multiple times
autoheader: `config.h.in' is unchanged
automake: unrecognized option -- `--force-missing'
Try `automake --help' for more information.
autoreconf: automake failed with exit status: 2

With the old autogen.sh that called the tools explicitly I get:

address@hidden:~/p/mailutils/trunk$ cat ../mailutils/autogen.sh
#!/bin/sh

aclocal -I m4
libtoolize --automake
autoheader
automake -a
autoconf
address@hidden:~/p/mailutils/trunk$ sh ../mailutils/autogen.sh
configure.ac:35: warning: AC_PROG_LEX invoked multiple times
autoheader: `config.h.in' is unchanged
configure.ac: 24: `automake requires `AM_CONFIG_HEADER', not
`AC_CONFIG_HEADER'
Makefile.am:5: require version 1.7.1, but have 1.4-p6
examples/Makefile.am:20: invalid unused variable name: `AM_LDFLAGS'

Does anybody have any suggestions?

Thanks,
Sam
