Due to r56561 change, VC6 fails to compile Module/posixmodule.c, becaue Crypt API needs _WIN32_WINNT  definition. I'll atach the fix patch.

1. Fix a typo in PC/pyconfig.h.
2. Still compile fails, because Py_BUILD_CORE seems not to be defined on VC6 build system. I greped, and found that it's only defined on VC8(PCBuild8/pythoncore/pythoncore.vcproj). Maybe it's right fix to define Py_BUILD_CORE on all platforms, but I don't know the meaning of this macro, so I simply reverted r55103 change which removed local _WIN32_WINNT definition in Module/posixmodule.c.

Mark, since this was your checkin: Can you take a look?

If not, please unassign.

This was my fault - Py_BUILD_CORE is defined in that same .h file - but after my new block which tested for it.  I'd forgotten the build systems still  define USE_DL_EXPORT instead of directly defining Py_BUILD_CORE and I should have checked.

The error was compounded by the fact that a VC2003 build does *not* require these definitions.  I can't see VC6 build files for the svn trunk, so I'm unable to test that posixmodule works with that compiler - but it *should* work, assuming my fix means that posixmodule will now see the #define in pyconfig.h

Fixed in r56624

Thank you, I confirmed your fix worked fine.
