Branches: main, 10.04
java/runtime/TypeInfo_Struct.java:
Collapse equivalences when comparing type_infos for equality.
java/runtime/TypeCtorRep.java:
Duplicate the required constants which otherwise are in
private_builtin.m. They should all be moved here but I don't want to
make that change on the 10.04 branch.
library/rtti_implementation.m:
Collapse equivalences in type_info_num_functors.
tests/hard_coded/construct_bug.m:
Use text streams in this test case, as the current hacky implementation
of `io.write_binary' doesn't work on the Java backend.
