--- Comment #18 from anlauf at gcc dot gnu.org ---

The patch in comment#16 seems to work and looks good to me, but it appears
to never have been submitted for review.

One could also add a mini-section in invoke.texi by borrowing from
gcc/doc/invoke.texi (-> Developer Options) and add a minimal example
for -save-temps in the context of gfortran use.=
