[Speex-dev] Fixed point bug in 1.1.6

[Tomasz Pyra]

Please compare samples:

http://www.ivo.pl/ivo2/sound/krwawa_org.wav
http://www.ivo.pl/ivo2/sound/krwawa_fixed.wav
http://www.ivo.pl/ivo2/sound/krwawa_float.wav

krwawa_org.wav is original file.
Both output files was created using same program by compressing from wav 
to speex, then decompressing from speex to wav (using speex_encode_int 
and speex_decode_int).

Only difference was used speex library.
krwawa_fixed.wav was created by libspeex compiled with defined FIXED_POINT
krwawa_float.wav was created without FIXED_POINT.

When samples values do not exceed (-32000;32000) eveything is ok.
Testing platform was Pocket PC, with ARM cpu, libspeex compiled in MsEVC++4.
