DELETE_ON_ERROR for phony targets

[Chad Loder]

Is there any way to emulate DELETE_ON_ERROR
for a phony target that creates a bunch of
files which are not specified as targets?

I've got a nice Java build system, but for
clean builds, I invoke the Java compiler on
a per-directory/wildcard basis, otherwise
it's just horribly slow.

I'd like to be able to interrupt the build
process with Ctrl-c, but I don't trust java
compiler to delete half-compiled files.

Thanks,
