[Swift-devel] struct mapping code that formerly worked now fails

[Mihael Hategan]

Yep.

Should be fixed in swift r3561.

I moved some of the functions in vdl-int.k and vdl.k from karajan to
Java for performance purposes. Some things got broken in the process.

Let me know if you find more things like this.
