changes in particular, clearly the old comment was correct. With
--disable-checking --enable-stage1-checking defaults to yes,types and because
of this #ifdef stage1 behaves differently from stage2. But it is certainly bad
even if --disable-checking compiler behaves differently from
--enable-checking=yes one.
If I replace #ifdef ENABLE_CHECKING with #if 1 // ENABLE_CHECKING,
--disable-checking bootstrap succeeds just fine.
