Update of bug #53922 (project octave):
Status: Need Info => Confirmed
Summary: unset case sensitivity => unsetenv does not unset
environment variables on Windows
_______________________________________________________
Follow-up Comment #2:
Ok, now I see that Octave uses Gnulib's 'putenv' function, which calls the
Winows function SetEnvironmentVariable, which is probably where the case
insensitivity comes in. But Gnulib's 'unsetenv' function iterates over the
'environ' global variable directly, and doesn't seem to correspond to anything
set with SetEnvironmentVariable.
It looks to me like 'unsetenv' simply does not work at all with 'putenv', even
ignoring case sensitivity. The 'unsetenv' function simply does not work on
Windows right now.
