[Octave-bug-tracker] [bug #53922] setenv/unsetenv are case sensitive on Windows while getenv is case insensitive

[Mike Miller]

Follow-up Comment #14, bug #53922 (project octave):

Yes, the POSIX documentation instructs programmers to prefer 'setenv' to
'putenv'. However, if you look in the Gnulib source code, the 'putenv' wrapper
function is the only one that references the Windows API function
SetEnvironmentVariable. And I can't tell if that's a benefit or a liability.

The Gnulib docs and code don't make it clear which of these functions should
be used together or what the expected behavior or compatibility is.
