Follow-up Comment #8, bug #61393 (project octave):

That made it go a bit further:

IIUC, `setenv` is a POSIX function that isn't available on Windows. But there
are implementations, e.g., in gnulib if you'd like to use those. 
Afaict, `putenv` is available on POSIX and Windows platforms as another
possible replacement:
https://pubs.opengroup.org/onlinepubs/009696899/functions/putenv.html
https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/putenv-wputenv?view=msvc-170

(You don't need the leading underscore for MinGW.)
