WANTED: SQL-Grammar specification for YACC

[Martin Weitzel]

Excuse for crossposting this to several groups, but for as much as I know
there is no group which is fully appropriate for this.

Does anybody know where to get a machine-readable grammar specification
for the SQL-syntax? YACC-source would be preferred but other styles were
also acceptable.
