[Mono-osx] IOKit Enumeration

I haven't had much time to work on this the last few months, but this
weekend I was finally able to enumerate RS232 ports using P/Invoke to
IOKit/CoreFoundation. This would work for enumerating any items in the
IOKit database but I want to add support for
System.IO.Ports.SerialPort.GetPortNames() to Mono for OSX. This works
quite well with any FTDI type chips that provide a virtual com-port for
communication, which is a common method of USB enabling devices.
I do a lot of embedded development and talking to our hardware is
important, and in future products we would like to ship software for OSX
So before I start integrating this code into my local checkout, I wanted
to ask what the best method is for adding this to the Mono codebase. Is
there a define for managed code on OSX builds? I've noticed that a lot
of places a runtime check is used against Environment.OSVersion.Platform
to decide which logic to execute, is this the preferred method in
managed code as opposed to conditional compilation?
Also, I have made some base classes that I use to manage reference
counting and to make the P/Invoke to CoreFoundation objects and IOKit
objects easier (e.g. CFString, CFMutableDictionary, IOObject). Is there
an OSX helper library similar to PosixHelper that this code would go in?
Thanks for any feedback,
