Multiple descriptions for fassert in gcc/d/lang.opt and gcc/java/lang.opt

Multiple descriptions for fassert in gcc/d/lang.opt and gcc/java/lang.opt

[Zopolis0]

While trying to compile gcc with gcj re-added, it breaks on there being
multiple declarations of fassert in gcc/d/lang.opt and gcc/java/lang.opt.

options.cc:3241:2: error: #error Multiple different help strings for
fassert:
 3241 | #error Multiple different help strings for fassert:
      |  ^~~~~
options.cc:3242:2: error: ‘Generate’ was not declared in this scope
 3242 |  Generate code for assert contracts.
      |  ^~~~~~~~
options.cc:3242:11: error: expected ‘}’ before ‘code’
 3242 |  Generate code for assert contracts.

Given that both of these definitions seem to be necessary, how do I resolve
this conflict?
gcc/java/lang.opt
fassert
Java Var(flag_assert) Init(1)
Permit the use of the assert keyword.gcc/d/lang.opt
fassert
D Var(flag_assert)
Generate code for assert contracts.

Is there a project adding gcj back to GCC?

If yes, it's better to discuss in gcc@gcc.gnu.org.  gcc-help is
generally for "help in building or using GCC."

Otherwise, you can't just inject some code died five years ago into the
current GCC tree and expect it to work.

No project, just me :p

I was asking in gcc-help because this isn't an error related to gcj
specifically, as it applies to any scenarios where there are multiple
definitions for the same thing in different lang.opt files. I've gotten
everything else to compile (bar libjava, haven't started that yet) with a
hack commenting out one of the definitions though, so I'm wondering about
the best way to resolve this conflict.

You can look at how d/lang.opt handles this for its conflicts with C.
Warning: it is very underwhelming :-)  It does require the documentation
to be the same for both languages, which probably is a good idea anyway.
