My i686-linux build configured with

--enable-checking=yes,rtl,extra --enable-libstdcxx-backtrace=yes
just died with

supposedly because of this change.
Do you really need those includes there?
If yes, what is supposed to ensure that the generated includes
are generated before compiling files which include those?

generated_files var which includes among other things insn-opinit.h,
and

rule, plus I see $(generated_files) mentioned in a couple of dependencies
in gcc/m2/Make-lang.in . But supposedly because of this change it now
needs to be added to tons of other spots.
