Hi Eric,

Again, thanks a lot for your help!

Okay, it definitely is a Windows problem. If I run the following command
in a cygwin shell, everything works as expected:

maxima --very-quiet -r
'batchload("c:/Users/weiss/AppData/Local/Temp/babel-17716aLH/maxima-17716hCp")$'
nil

However, it does not work in a Windows shell. But this is no longer an
org issue.
