Don't we need to add support_idl_files here also?

[Nils Barth (inactive), 2013/10/23 08:13:17]

testing_support_idl_files includes support_idl_files,
so this is correct.
However, you're right that this is confusing;
I've rewritten it to make the sources/inputs & used variables
more transparent -- thanks!
