I working on getting the sources through the eclipse IP process.  We 
have one of two source trees approved at this point and, while it has 
taken a while to get this far, I expect the second tree to go more quickly.

There is a bootstrap to build the RTSC tools because we use the RTSC 
tools to build itself.

It is possible to help out now.  The RTSC tools include a number of 
native executables (e.g., xs, xdc, and xdcpkg, see 
http://rtsc.eclipse.org/docs-tip/Command_Line_Tools).  One of the first 
steps in the bootstrap is build these commands using the RTSC build 
engine.  In order for this to happen, we need a target and a platform 
for OS X.

Part 2 of the RTSC tutorial provides an overview and examples of what is 
required, but native targets are often _much_ easier that targets for 
embedded platforms.  My guess is that there is a gcc compiler for OS X, 
so it should be easy to create a target that inherits from 
gnu.targets.ITarget.  Since it's ok to only support Intel-based Macs (at 
least initially), we can probably just use the host.platforms.PC platform.

Once we have an OS X target, we can either put it in the gnu.targets 
package or create a new package and maintain it in 
http://dev.eclipse.org/svnroot/dsdp/org.eclipse.rtsc/contrib/targets/trunk. 
 The complete sources to the gnu.targets package are included in any 
XDCtools distribution (and will eventually be maintained in our eclipse 
SVN repository).

Beyond targets and platforms, there are a few other packages that will 
have to be extended to support OS X; e.g., all the graphical tools rely 
on SWT (which relies on some native code) but I assume the native code 
required for OS X already exists.

Bottom line: a good first step is to create a target and platform that 
builds one of the tutorial "hello world" examples 
(http://dev.eclipse.org/svnroot/dsdp/org.eclipse.rtsc/training/ec2009/trunk/src/part2/examples/hello) 
to run natively on OS X.
