Re: autoconf problem building

I added </dev/null (in aclocal.m4 I presume) as suggested, but it still hangs 
on the configure. I
don't know much about it as I don't use it, but it doesn't seem to accept any 
options I give it,
like -help, --version, -v, -V. When I run emacs, I can't CTRL-C out of it to 
get back to the shell -
it hangs - I have to kill the cmdtool (Solaris 2.6/7/8). If I run 
emacs</dev/null, I can CTRL-C out
of it. Unfortunately, I don't have any man pages for it. However, I just 
noticed we have a very old
version of MicroEmacs - I have MicroEmacs 3.6 installed (1990!!).

I will try installing the latest version and rebuild autoconf. Should this make 
a difference do you
