Sorry about that last patch, I hit the wrong one (my bison is
way out of date, so I'm hacking the resulting .c file for test
and backporting to the .y file, not that thats an excuse :)

Anyway here is a patch to 7.4b1 that seems to apply to the snap
from yesterday as well.

This allows you to
 EXEC SQL CONNECT TO :target as :connection_name user :uname using :password;

and have the uname and password C variables get passed correctly to the 
ECPGconnect fucntion after epgc processing.
