Using the flag, I built a 32bit Octave on MacOS 10.6.6 and encountered no 
problems.

I've asked Richard about his 64bit build. He did not use this flag, and did not 
include FLTK, but did use clang instead of gcc. I'll wait for his input before 
making any changes.

Regarding D__LISTS__, is this not needed for Snow Leopard?
