Did you tried to add switch -v to the btyacc command line ?

Not sure you speak above about "2 rules never reduced" :)
btyacc warns about following rules which is really never used:
ddl_subname_opt
: /* nothing */ { $$ = NULL; }
| ddl_subname
;
I failed to see where "ddl_subname_opt" is used. Probably it was created
initially
for use with "ddl_subname" rule ?
