Hello. This is follow up patch for current trunk.
I confirmed testall.py passes on VC6 except for
test_normalization.py. (I needed to expand python_d.exe's stack size to 1MB, though. otherwise,
test_excepsion.py etc crashes with stack overflow)

# error of test_normalization.py

I updated patch. To avoid conflict <winsock.h> and <winsock2.h>,
WIN32_LEAN_AND_MEAN is needed.

I updated the patch.
- Added missing _msi support
- Workaround for PC/msvcrtmodule.c (getwch not exists on VC6)

Sorry, I updated the patch again.
- Add Python/pystrcmp.c to pythoncore.dsp.
- Rev59671 contains intptr_t unavailable on VC6, avoid compile error by 
using PyLong_FromVoidPtr().

Ummm, I realized my change is probably inproper...

I recreated the patch against rev59669 for now. Please try my patch on 
that revision. Currently, VC6 cannot compile python on HEAD.

Umm, I found Py_intptr_t...
OK, VC6 can compile HEAD. Please forget previous patch. I confirmed 
test_long.py, test_math.py, test_builtin.py successfully runs.

I zipped PC/VC6/* as files.

Oops, sorry for double post. My network provider now stucks somehow...

Rev59716 required some fix.
I'm not sure the patch for Lib/socket.py is apropriate.

Please don't apply this patch now.
VC6 build fails from rev.60696

issue2065 contains the patch for this branch too, so I'll close this issue.
