  Ah, your right. This seems to work. Shouldn't have blamed automake for

  Do you think it would make sense to somehow have TESTS_ENVIRONMENT
  *default* to wine, for this type of cross builds?
Perhaps.  Is this common enough to add special magic?

  As I said, I haven't yet installed any 64-bit enabled wine. I don't
  doubt that w32 builds work, I have just have never tested that, and I
  think it helps if it can be easily tested without the need for a windows
  box or d:o license. Are there any w32 tests in the nightly builds? Using
  wine makes that easy, even if that's not a 100% substitute for testing
  native builds.
The only Windoze testing in the nightly builds is for 64 bits.  (This is
done on almost real hardware.)

I put on my TODO list after you sent your initial message to setup
nightly testing using wine.  Does user-level instructions run natively
on the CPU, or is there qemu-like translation going on?

  Could of course be a bug in wine, if these tests succeed on native

You are of course most welcome to debug these failures...
