 Patch updated and attached.

I've ran pretty much all the tests and quite frankly, they are manual, human-graded tests. There is no unified way to tell if a test passed, etc. That might be why there is no test target.

I modified your suggestion a little to more resemble the specs' language: http://quadium.net/funge/spec98.html

Mea culpa. I mistyped that.

The tio.run links linked from those two Befunge-98 examples use the FBBI fingerprint, which currently isn't supported by cfunge. I tested a few examples from  https://esolangs.org/wiki/Befunge  and everything seems to work fine.

Not a bad idea, though toys.scm somewhat fits. Please add the new file
to the list in gnu/local.mk, though.

Also, could you run your code through etc/indent-code.el?

The repository does contain a tests/ folder, did you try running these?
You can check the rgbds package from assembly.scm for some inspiration
as to how you can handle a custom testsuite entrypoint.

It would be nice to define what a fingerprint is, as even though there
was once a summer when I was fluent in Befunge, I still needed a longer
moment to recall what those are. How about this Texinfo markup?

@dfn{fingerprints} (opt-in language extensions identified by a
four-character code).

COPYING and the headers in src/*.c (well, I checked diagnostic.c)
suggest that it's actually gpl3+, what gives?

Could you send an updated patch?

P.S. I tried to test the package by running this CGCC answer in it, but
it loops infinitely. I didn't have time to debug this, so I don't know
where the blame lies.
