Follow-up Comment #55, bug #49718 (project octave):

@Markus: Ok, so the explanation is just above. We use ghostscript as an
intermediate to write the gl2ps inputstream to an eps file:

  ## As epstool does not work with pipes, a subshell is used to
  ## permit piping.  Since this solution does not work with the DOS
  ## command shell, the -tight and -preview options are disabled if
  ## output must be piped.

  ## DOS Shell:
  ##   gs.exe [...] -sOutputFile=<filein> - & epstool -bbox -preview-tiff
<filein> <fileout> & del <filein>

The following change will remove the spurious temporary file name. Does it fix
the eps outputs?
