That thread discusses their implementing sbrk as always returning 0 or 
something trivial like that, purely to pacify broken applications that 
use sbrk (0) to estimate memory usage and fail to build if sbrk does not 
exist. Such a workaround obviously won't get Emacs running. In contrast, 
Daniel's proposed patch should work.
