I have the encoder and decoder running now and have verified that the
encoder is bit-exact wrt to the fixed-point code running on x86 for the
same 30-second audio sample. Encode and

I looked at the patch. Seems mostly OK, though there are some minor
issues. First, I don't think it's right to say spx_int_32_t=long except
for alpha. This will likely cause problems on Itanium, Power64, SPARC64
and probably x86-64. I suggest either an explicit check for C55xx (and
later others) or a test in configure.ac.
Also, I'm not sure I get your use of "+#ifdef UNUSED" in the SpeexBits
code. Finally, there's a few changes which I think should be removed,
like for speex_all...

if we can speed it up.
