jdbc1 & debug

The jdbc1 driver would not compile until I modified Statement.java:

[javac]
/usr/src/postgresql-7.1beta4/src/interfaces/jdbc/org/postgresql/jdbc1/Statem
ent.java:284: Missing term.

was:
if (result != null) &&
((org.postgresql.ResultSet)result.reallyResultSet())

changed to:
if (result != null &&
((org.postgresql.ResultSet)result).reallyResultSet())

Also, I'm trying to run performance tests with 71b4 but I'm seeing many
debug messages. How do I turn off debug?
I ran:
./configure
gmake
gmake install
etc.

Is the default for WAL_FILES zero? Should I be concerned with this message?
DEBUG: XLogWrite: new log file created - try to increase WAL_FILES

Thanks,
