I found something surprising while using this patch: it can't be used in
a .y file, due to the malloc->xmalloc renaming done in the .y.c rule.
I puzzled over the error about "unique_xmalloc_ptr" for a while until I
remembered this.

One option would be to fix up that renaming, maybe something like:

-	     -e 's/\([^x]\)malloc/\1xmalloc/g' \
-	     -e 's/\([^x_]\)malloc/\1xmalloc/g' \

Another would be to rename the class unique_xmalloc_ptr after all.
