Thanks, Joel.

FYI, now, using the latest sources from git,
when I bootstrap, run ./configure --enable-gcc-warnings
and then make and "make distcheck", I see this:

/bin/sh ../build-aux/ylwrap ../src/parse-gram.y y.tab.c src/parse-gram.c 
y.tab.h src/parse-gram.h y.output src/parse-gram.output -- tests/bison -y -dv 
--warnings=all,error --report=all

I haven't had time to delve into it, yet.
