Other than the fact that it's about a factor of 16 slower than bison
1.28, while not offering any substantial gain in functionality?  If I
were a Bison maintainer, I'd hang my head in shame.

All PG regression tests pass here with 1.75-built parsers.

Same here on a Red Hat 7.3 system.

In case anyone is interested, I made a bison 1.75 rpm based on the 1.35 source 
rpm from RH7.3. It can be found here along with an updated src RPM:

16x is the grammer output generation, not the actual parsing of the SQL,
right?  There are cases where slow output generation can lead to faster
parsing, right?  Let's hope that happened.
