Right now, the code *does* assume that a char is 8 bits. However, this
assumption is only made in the bit packet (bits.c), so it should be
fairly easy to make it work for a platform where a char is 16 bits.
Still regarding fixed-point, right now, spx_word_16 is defined as
"short" and spx_word_32 is defined as "int", but that's
only in arch.h
and eventually, it should be replaced by something a bit better.

On a related point, has anyone ever compiled FIXED_POINT Speex on a 
system with 16-bit chars? Will it definitely work, definitely not work, 
or might it work and no-one has any idea? :-)

More specifically, I'm trying to decode Speex data encoded using 
sampleenc. So, it's definitely been encoded correctly. Normal (floating 
point) Speex compiles and decodes that data fine on the platform.

Does no-one have any idea here? Grepping the libspeex sources for
"char"
produces several references which imply that the code assumes a char is 
8 bits. Jean-Marc: would you say that this is an assumption that the 
code makes?
