Oops, sorry for lack of explanation.

-fno-jump-tables (**not** -Wno-uninitialized) is
workaround for build failures of huge generated files,
reported as [2] in README.gcc14:

```
[2]: new GCC generated files are too huge, eg:
     {standard input}: Assembler messages:
     {standard input}:60465: Warning: .word .L5289-.L5291+00000000 
didn't fit
```

Note that we have already applied -fno-jump-tables hack
to other source files for GCC12/m68k.

Thanks,
