This issue will not be resolved in GCC 4.1.0; retargeted at GCC 4.1.1.

Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.

This still fails on the mainline.

This still fails because it hasn't been fixed ;-).  My patch for
-feliminate-unused-debug-types only handled casts.  It needs further front-end
work to handle enums.  At least the infrastructure is in place for the
front-end work.

------- Comment #8 from drow at gcc dot gnu dot org  2006-07-22 18:06 -------
Hmm.  What's happening here is that we set TREE_USED on the enumerator, but not
on the type.  The enumerator never gets output, because the type is not output.

It would probably be a strict improvement to add the type to the used_types
hash table like we now do for casts.

However, that is not a great solution either.  It won't cause the enum to be
emitted for "static int x = JTI_MAX;" at the global scope even if x is emitted.
 We really need a more general solution to this...

Meanwhile, I'm testing a patch to treat them just as well as we treat casts.
