I haven't update master very recently but a while ago I got into the
habit of running a script before calling `make'. the $1 parameter is the
path to src/lisp. it lists stale elc files, which I then delete by hand.

```
for i in $(find "$1" -name \*.elc); do
	j=${i%c};
	if [ ! -e "$i" ]; then
		echo "MISSING $i" >> /dev/stderr
	elif [ ! -e "$j" ]; then
		echo "MISSING $j" >> /dev/stderr
	else
		# file-newer-p.sh $j $i  # UNTESTED.
		a=$(stat -c '%Y' "$j")
		b=$(stat -c '%Y' "$i")
		if [ $a -gt $a ]; then echo "$i"; fi;
	fi
done
```

Since I started doing this, I don't think I've faced elisp recompilation
problems. But I never understood the rationale for "loading stale elc"
behaviour as a part of recompilation.  If someone can explain that I'd
appreciate it.
