No: /gnu/store/640hfpr069hvqv9gcs0ayq0is21zfii6-libgccjit-
10.3.0/lib/gcc/x86_64-unknown-linux-gnu/10.3.0

The style changes are not the only thing at play here, though.  In
particular, I am trying to build Emacs 28.1, whereas Andrew builds
other versions, though notably the newest one ought to include the
smoke test.  You could also try other combinations for libgccjit and
gcc to see if those make a difference – last time I tried it did not.

Attached the definitions as a file this time.
