==================
I need a better solution today and the distribution assumptions won't do.

As I see it there's an entanglement between:

1. Header files provided by Windows compiler
2. Presence or absence of Platform SDK
3. Presence or absence of IPv6 on platform
==================
Here are the use cases I've encountered:

Microsoft Visual C++ 6.0 out of the box requires HAVE_PLATFORMSDK be
UNDEFINED or the compile errors are messy which leaves CCXX_IPV6 as
UNDEFINED also.

Borland C++ Builder 6 out of the box requires HAVE_PLATFORMSDK be
DEFINED or the compile errors are messy however the link fails on
Windows 2000 due to the lack of 2 symbols for IPv6 structures as
Windows 2000 doesn't officially support IPv6.  To compile and link
on Windows 2000 I must UNDEFINE CCXX_IPV6 also.
==================
IMO HAVE_PLATFORMSDK & CCXX_IPV6 should be independant variables.
Both should *always* be defined as 0 or 1 so both can always be
exposed and controlled in the build files so source code edits are
no longer required.

I'd like to see if I can make HAVE_PLATFORMSDK go away altogether.
