Dear Siep Kroonenberg,
So this has been observed before. As I already mentioned, MiKTeX does
return the value set by setenv. So does Linux, as I just tested.
A difference may be that I'm using a dynamic library for lua52.
I think it may be possible that TL/w32 is right and MiKTeX and Linux are wrong.
If you need values of variables setenved in the current
process, please initialize kpse and use kpse.var_value().
FYI, os.getenv() is defined in the lua52.dll and os.setenv()
is defined in the texlua.
Thanks,
Akira
