[Speex-dev] Please test upcoming release

The trouble is that one cannot identify the type difference without reading 
the nb_celp.c source file, and this parameter is treated differently than 
other, similar parameters.  It would seem like the most intuitive approach 
would be to match the interface to the structure.

This is a trivial point, of course.  I have attached a patch to the two TI 
interface files, which adds the configuration for the filter, sized as 
spx_int32_t.  I also included the modified files (I know that you have had 
some trouble with patches that I have sent before).
