Issues with the latest 6.5 source

I refreshed my 6.5 source last night (last time was early April). This had
some patches to case and coalesce that I needed. This is working great
except for the following two areas:

1) The \g option in pgsql is failing. I have been using this technique
for months to create a script file from and SQL statement and then execute
the file. Here is the steps that worked before I pulled down code last
night:

\g sip_revoke_all.sql
unexpected character Z following 'I'

Once the above error occurs, the script will hang
until I manually break (ctrl-c).

2) My Access97 application using ODBC can't connect to the database.
Nothing has changed other than rebuilding the source. In attempts to fix
this, I and destroyed my databases, rm $PGDATA, and performed initdb. I have
verified that pg_hba.conf is correct before and after recreating my
databases. The Psqlodbc.log log file is below. I can log onto the
database using psql on my linux workstation just fine.

Has anything changed in the code recently (within the past 3 weeks) that
could have had some effect these two conditions? I am at a complete stand
still until I can get my ODBC issue resolved. I can work around item 1.

Thanks Michael
