Well you won't find a win.exe on an NT-based system.  But I don't think 
a system will run very well if WINDIR is not defined.  I'm thinking you 
should assume WINDIR will always be defined (can somebody prove that to 
be a bad assumption?) 

Same goes for EUDIR... if not defined, assume that Euphoria is not 
installed (at least it's not properly installed).
