SnowLeopard ant build of apps for java 1.5 on 10.4

I'm trying to figure out how to build WO 5.3.3 apps under 10.6, to be deployed on 10.4 (with java 1.5). I would normally build my apps on the development box with ant, then move them over. I got the impression from something I read (no idea where, now) that you could use Snow Leopard's java 1.6 compiler to build 1.5-compliant apps. I don't think the Eclipse Java -> Compiler -> compliance level affects what ant does, neither from within Eclipse, nor (of course) from the command line.

I've seen suggestions to add source and target attributes to the wocompile task. I assume that means something like this:
<wocompile srcdir="Sources" destdir="bin" source="1.5" target="1.5">


But that doesn't seem to have an effect.... "file" still reports the .class files as being version 50.0.

I also saw a suggestion to pass -source and -target to ant, but I don't understand that: those aren't valid ant parameters.

I suppose I could install an old java 1.5 compiler on Snow Leopard. Is that the only way?
