What happens when you just touch params-list.h or params.def?
move-if-change will leave the target untouched when unchanged (that's
the whole point of it), so it will remain older than the dependencies.
I could reproduce the problem using these instructions, thanks.
I also found a bit "On the use of stamps" in gcc/Makefile.in, which
explains the problem and how to fix things.
Updated patch accordingly.
OK for trunk if bootstrap succeeds?
Yes.
