I was confused by 0001, because with the present test setup that will
result in creating an extra tab_comp_dir that isn't inside tmp_check,
leading to needing cleanup infrastructure that isn't there.  However,
0002 clarifies that: you're redefining TESTDIR.  I think 0001 is OK
as long as you apply it after, or integrate it into, 0002.

I see some references to TESTDIR in src/tools/msvc/ecpg_regression.proj.
It looks like those are not references to this variable but uses of the

 <PropertyGroup>
  <TESTDIR>..\..\interfaces\ecpg\test</TESTDIR>

thingy at the top of the file.  Still, it's a bit confusing --- should
we rename that?  Maybe not worth the trouble given the short expected
lifespan of the MSVC test scripts.  0002 seems fine otherwise.

No particular opinion about 0003 -- as you say, that's going to be
gated by the buildfarm.
