>_POSIX_PATH_MAX is 256, so there's no reason to make it longer than that.
On my system (Linux Mandrake), MAX_PATH is 4096. That's NAME_MAX which 
is limited to 255. Why not set the length to the maximum length of the 
system blender is built on? Must this limit be the same for all systems? 
(actually I still haven't had enough time to see how blender stores 
informations to .blend files and what is stored. Since the absolute path 
does not make sense for a plugin, I'm not sure this path is stored in 
the .blend files. Is it stored?)

What does that means?

Thanks for your answer.
