Jean-Claude,

I'm surprised.  I would have expected TARGET=94 or TARGET=0.94 to be accepted.
The "%" is improper and should not be included.  However, I tried this and
I see the same behavior you do. I have filed a ticket on this issue and it
should be fixed by 1.5.1. In the meantime you can just ignore this warning.

The validation of creation options is new in GDAL 1.5.0.
