AFAICT, the API should be consistent, although there may be other
issues, e.g. compilation and linking switches. There's also the issue
of whether the driver has ever been tested on Windows or with common
Windows databases.

It's a moot point now that Markus has back-ported the changes, but
they should be safe for inclusion.

The Unix-isms which had to be worked around are (AFAICT) all in
"peripheral" functionality, i.e. monitoring resource (CPU, memory)

Most of the changes were essentially:

	#ifdef __MINGW32__
	<stub definitions>
	<real definitions>

On Unix, the changes shouldn't have any effect. On Windows, the worst
that can happen is that it doesn't work (although it should at least
compile now), although it's more likely to just be that the resource
statistics will be inaccurate (e.g. memory usage reported as zero, CPU
usage measured in whole seconds rather than microseconds).
