[Nel] Trouble compiling NeL's AI module on RedHat Linux 7.3

[noname]

Hello,

An error occurs while compiling NeL with AI enabled. I use gcc-2.96 and 
had no issues compiling NeL without AI.
Please don't answer that I don't need AI because Snowballs doesn't. I 
need it.

Here is the compilation log:
