Houston, we have a problem:  paths are handled differently between OS 9 
and OS X.  We could account for that difference if we had a way of 
knowing whether the engine is running in OS 9 natively or under OS X's 
compatibility layer, but alas "the systemVersion" returns the same 
number when booted into OS 9 natively or when running under OS X.

What's needed is a function added to the engine to let us know whether 
we're native or under OS X when running OS 9 and earlier.

What should it be called, and who wants to add it to Bugzilla?
