Problem with --version after compiling autoconf

[Andy Armstrong]

I want to update from autoconf 2.62 to 2.69.

I downloaded the source and ran the following:

./configure
make
make install


These all complete successfully.

When I run autoconf --version I get the following:

autoconf --version
autoconf (GNU Autoconf) ?K??
Copyright (C) 2012 Free Software Foundation, Inc.

The problem you see here is that the version reports as ?K??.

Why could this be? My machine runs in the EBCDIC codepage and I am wondering if 
this could be associated. Is there a configure / make option I need to add.

This issues stops me compiling other software, as the configure scripts check 
the version autoconf reports and it ends up failing those checks.

Please help!
