Says it all really. I can't figure out how to stop --gnu being passed
to m4, and with it, it fails.

$ /usr/bin/m4 --version
m4 (GNU M4) 1.4.11

I compiled 1.4.14 in /usr/local/bin but this doesn't seem to be
getting picked up by autogen.sh

$ which m4
/usr/local/bin/m4

I'd love to get this to work. Can someone help?

It would be more interesting to know which version of autoconf you
are using. Also, send the output of "env".

Actually, it seems that autoconf's configure checks whether m4 accepts
--gnu, so apparently your autoconf was compiled in the presence of
some other version of m4. Try reinstalling autoconf.

Hi Sven,

Thanks for the quick response. You were absolutely right. I was using
the autoconf that came with my distribution (Ubuntu 8.10). I've
compiled a slightly newer version from source and it all works fine.
