Code for identifying mac OS X does not seem to do so
consistently. For example in e-macs.el we have:
emacro/e-macs.el:(when (not (eq system-type 'darwin)) ;
OS X console hates scrollbars
emacro/e-macs.el: (string-match "darwin"
We must standardize the code for identifying a OS X system
(maybe set a variable at one place and check for the
variable everywhere else).
