This is with a Microsoft server v9.0.2047 x86, using TDS 8.0.

The placeholders are working just fine, with the exception of
stored procedure calls. In that particular case, things only work
if you're only using one placeholder. (At least, this was the case
with tdsodbc v0.63-3.2. I haven't tested it with v0.82-5 yet).
But that's another story :)
