[PATCH 1/1] revert AC_PREREQ to 2.63

[Andrei Kholodnyi]

Hi William,

I confirm, it does not work on my old notebook with Ubuntu 9.04 installed.

configure.ac:4: error: Autoconf version 2.65 or higher is required
configure.ac:4: the top level
autom4te: /usr/bin/m4 failed with exit status: 63
aclocal: autom4te failed with exit status: 63
autoreconf: aclocal failed with exit status: 63

It will probably work on 10.04, but I didn't try it yet.

Andrei.
