Hello Stefan,

Sorry for my late reply, but I've welcomed a tiny (for the moment, only)
upgrade to our family last week...

This suggestion and the previous one are perfectly working. Thanks a lot...

The only thing I dislike in this one is the way we write the expansion: I
always find it hard and unintuitive to read something like

  (expand-file-name "SumatraPDF/SumatraPDF.exe" windows-program-files-dir)

instead of a more natural syntax (directory, then file):

  (expand-file-name windows-program-files-dir "SumatraPDF/SumatraPDF.exe")

I know this may sound stupid, and purely syntactic...

Anyway, things are like that... and thanks once again for mentioning ways to
the portability of my .emacs file!

Best regards,
Fabrice
