[PATCH] update configure.ac to autoconf 2.61

[Felix Zielcke]

Attached patch is generated via `autoupdate --force' from autoconf 2.61
a svn-diff after ./autogen.sh doestn't show anything more, because
the ./configure script in SVN is already generated with autoconf 2.61.

autoconf 2.61 is dated 17.11.2006 on ftp.gnu.org

Debian etch + lenny have autoconf 2.61
etch has been released 8th April 2007
Ubuntu has it since feisty which has been released 19th April 2007

I haven't checked the others but I think this is recent enough for the
configure.ac (remember it's generated by ./autogen.sh anyway)

Yes I really want to get rid of old stuff and if you even only need to
call `autoupdate --force' ;)

Debian experimental has autoconf 2.62 which I normally use, there is
some other stuff deprecated and so changed by `autoupdate' but I'll
leave that for the future.
