We are not talking about the OS, we are talking about the programs
that set and query environment variables using 'getenv', 'putenv', and
other similar APIs, followed by simple string processing.  And those
are definitely _not_ treating the separator as opaque, something you
can easily verify both by looking at the sources of the respective
applications, and by simple experiments.

And in that sense, the path separator character is always ':' on Posix
systems and ';' on MS-Windows.  So I think Guile ought to have such a
variable; Emacs, for one, does.
