--- Comment #2 from vries at gcc dot gnu.org 2011-04-05 16:01:17 UTC ---
The function emit_use_return_register_into_block is only used in code guarded
with HAVE_return, and therefore the definition of
emit_use_return_register_into_block should also be guarded with HAVE_return.

Failing to do this caused the error mentioned in the description field.

This is fixed by the check-in in comment 1.
