Good news ... the recent suggested revisions permit Emacs master branch (0b9b363dabd70032a288e14333896022caa2d252) to build successfully on OSX 10.6.8 and create working version of Emacs without any immediate crashes on launch.  I only tested M-x butterfly and a dired-mode buffer, but the major hurdles appear to be resolved.  To help ensure that everyone is aware of the exact changes that led to a working version of Emacs, attached is a diff patch.

Thanks,

Keith
