What about reduce and shift conflicts, any bison expert here?
Shift/reduce and (for GLR parsers, which that sqlbison.y is)
reduce/reduce conflicts are somewhat common and expected, so there's
even %expect and %expect-rr declarations that specify the number of
expected sift/reduce and reduce/reduce conflicts, respectively, and
Bison will then only warn if the numbers are wrong. Though, of course,
somebody familiar with that sqlbison.y should probably have a look
before blindly adding such declarations to silence the warnings.
