Unfortunately, LANGUAGES="c c++" didn't help.
I believe I've tracked down the problem, a missing check for languages
selection in gcc/f/Make-lang.in . Below is a patch. This is my first
attempt at creating one, so if I did it wrong, please straighten me
out... :-)
(By the way, it would help novices such as me if someone could put a
paragraph or two in some "README-creating-patches" file. Trying to
guess the right "diff" switches was a bit tricky.)
