opus - Sep 2010 - Linking multiple versions of CELT in same executable

Hi,

I have a couple of questions

1. Is there a way to build CELT which will allow me to link multiple versions of
CELT in the same executable?
I need that to support older content and when we move to newer CELT versions.

2. I was looking through the archives and found one patch from Thorvald at
http://lists.xiph.org/pipermail/celt-dev/2009-November/000241.html

But, looks like that is only for library names.
Also, I tried building 0.8.1 on linux/x86/32-bit and it just built libcelt0.a 
and not libcelt081.a.
LIBCELT_SUFFIX was set to 0 in Makefile.

I configured it using
./configure --enable-static=yes --enable-shared=no --enable-fixed-point

I do not know what I am doing wrong to get the incorrect suffix.

Can you please help?

Thanks,
-raja.
