Can something like this be done?

-- what I am trying to say here is:
-- if you Window's return of -1 can mean either that
-- the env variable has not been set, or it is empty,
-- then conform the innocuous ambiguous value to something 
-- cross_platform compatible

if equal(getenv(name),-1) and platform() < 3
then return {} -- or " ", if necessary (essentially what George suggested)
else return getenv(name) end if
