FWIW, I downloaded Visual C++ 2005 Express edition, and the latest
platform SDK, and had a go at building Python trunk.
I just followed the build instructions from PCBuild\readme.txt as best
I could - of the optional packages, I only got zlib to work. The
issues with the other modules may or may not be serious - for example,
bzip2 is now at version 1.0.3, and the old source isn't available.
Just renaming the directory didn't work, but I didn't bother
investigating further.
I applied the patch you mentioned, but otherwise left everything unchanged.
The project file conversions seemed to go fine, and the debug builds
were OK, although the deprecation warnings for all the "insecure" CRT
functions was a pain. It might be worth adding
_CRT_SECURE_NO_DEPRECATE to the project defines somehow.
I then ran the test suite, which mostly worked.
Results:
235 tests OK.
5 tests failed:
test_asynchat test_cookie test_grammar test_mmap test_profile
58 tests skipped:
test__locale test_aepack test_al test_applesingle test_bsddb185
test_bsddb3 test_cd test_cl test_cmd_line test_code

test_scriptpackages test_signal test_socket_ssl test_socketserver
test_sunaudiodev test_threadsignals test_timeout test_timing
test_urllib2net test_urllibnet test_xdrlib
7 skips unexpected on win32:
test_hashlib test_cmd_line test_xdrlib test_code test_float
test_coding test_functional
I'm not sure what to make of the "unexpected" skips...
The output for the failed tests was:

I don't have time to investigate much further, and not all of these
look to be VC 2005 Express issues (for example, the test_profile and
test_cookie errors look like code issues rather than compiler ones),
but I don't have an alternative compiler to check.
I hope this is of some use - it would be brilliant if VC 2005 Express
could be a supported build environment. (Of course, MS have updated
the CRT again, so binaries built with VC 2005 Express aren't binary
compatible with extensions built for the standard release... :-( )
Regards,
Paul.
