"It might be good to consider that environment variables make sense in DOS,
DOS with PharLap extender, DOS with Desqview extender, DOS with Desqview/X
extender, Windows NT, OS/2, VxWorks, and other operating systems. Are there
any operating systems or remote target (embedded) runtime systems that
do not provide environment variables?"

Very few remote target (embedded) runtime systems have environment
variables and many operating systems do not. If they were standard
they would be in the standard libraries.

They are standard in ANSI, but with entirely implementation defined
semantics.
