I have done this (with gdal-CVS from 17.11.2006). There are several
results which I try to summarize now:
The described problem above is away now, but another problem appears
which I stumbled over in gdal 1.3.2 as well. Therefor I decided to use
gdal 1.2.6 which works as expected in my app.
When using the latest CVS with my join example I received this error:
ogrinfo -al join_together.ovf
ERROR 4: Update access not supported for VRT datasources.
Had to open data source read-only.
INFO: Open of `join_together.ovf'
using driver `VRT' successful.
Layer name: join
Feature Count: 16
ERROR 1: Not enough tokens to complete expression.
This was know to work with 1.2.6 except the rounding problem.

I have bundled up a minimal example with a Mysql-Dump (containig one
table with 3 rows) and an unfree sampledataset where you can reproduce
I have sent you the dataset via PM.
