The first challenge would be in getting the shared libraries to
compile on Win32.  I don't think the "build environment" has been
updated to cope with that.

Notice in that regard that we've seen a little bit of breakage with
the AIX support recently (nothing really FRIGHTENING, and there was a
pretty easy workaround, but it did break, and I expect it is still
"broken"); getting Win32 support into place on the build side is
likely to take some thought that simply hasn't gone into it yet.

Similarly, some of the components do assume the availability of fork()
(e.g. - slonik.c) that may function differently on Win32.

Thirdly, ZERO effort has gone into producing scripting tools that can
"play well" on Win32; it's probably not reasonable to assume having
Perl or much of anything else around of a "Unix nature" in a Windows
production environment, so that some new efforts would presumably have
to arise there.  Probably some VB scripts, or similar.

None of these things represent insurmountable, intentional, or
particularly enormous roadblocks, but nothing is likely happen until
someone that wishes there to be a win32 version decides to do more
than to merely "wish."
