  Hi, Vladimir.
  I ran the tests today with CVS head, using all versions of MSVC on
my machine. The commands were
      set DO_DIFF=diff
      test_all.py msvc-6.0 > msvc-6.0.txt 2>&1
      test_all.py msvc-7.1 > msvc-7.1.txt 2>&1
      test_all.py msvc-8.0 > msvc-8.0.txt 2>&1

  There are errors and failed tests, but the results are pretty much
the same with all these compilers. Attached is the MSVC 8 output.

  I also ran the pch.py test with the command lines
      pch.py msvc-6.0
      pch.py msvc-7.1
      pch.py msvc-8.0
  and they completed fine, after I patched pch.py to use #include
"pch.hpp" instead of #include <pch.hpp>. The patch is also attached.
