Yes - I rearranged it that way for this thread.

However, it's best served/combined with the alltaptests patch :)

Right - I'd incorrectly set test_dir to t/ rather than the parent dir.

That patch only dealt with TESTDIR. PATH was still set by makefiles.
For MSVC, it was being set to top_builddir/tmp_install.

I've added a 2nd patch to also set PATH. Maybe it should also set
PATH=$bindir:$PATH - I'm not sure.
