[Speex-dev] Compile Speex for Blackfin in VisualDsp

[Software Engineer]

Hi,
 
Is there a fix for this issue?   ---> http://permalink.gmane.org/gmane.comp.audio.compression.speex.devel/2959
 
I am seeing the same thing when I compile speex in visualdsp
 
These are the errors I get from using the assembly version of vq_nbest:
