Excellent job fixing the problem!

A note to whoever ends up committing this: This bug also exists in 1.8, 12, and trunk. The 1.8 fix is exactly the same as this one. The 12 and trunk fixes will be slightly different since the update_odbc() callback takes an ast_variable list instead of va_args. The fix is still very similar though.
