There is a problem with using some optimizations on some of the source 
files.  You can try different configurations, but using the "omit frame 
pointer" or "generate intrinsic functions" are the two that cause the 
most problem for me.  Plus, a lot of the POV code has aliased variables 
(in an attempt to speed up the code) that confuses most compilers, so 
you should use the appropriate switches.
