* configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare

Browse Source 
rather than -W, so we don't get bogus warnings about sign comparisons.
Add -Wpointer-arith, since that warning is useful (it reports code
that does not conform to C89 and that some compilers reject).
* data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
since it's no longer needed.
