[Bf-committers] 64 bits Blender

I cannot emphasise enough that Blender is not 64 bits safe yet. Files  
you write with 64 bits Blenders now might corrupt 32 bits Blender  
versions. Using library referencing won't work, and not to forget the  
code itself isn't 64 bits safe, meaning you most likely won't have the  
possibility to reliably use  up to 8 or 16 GB memory.

To warn developers/users for this situation I've added a line of code  
in Blender that exits when you compile a 64 bits, with this message:

"64 bits compiles will give incorrectly saved .blend files. Do not use  
it. For testing purposes please remove this line from creator.c"

This exiting is a bit unfriendly yes, but it's easy to locate this line  
and remove it for your own compiles. At least people then cannot claim  
they didn't know. :)
