GWorkspace porting troubles

[LHelldorf]

I am in the very early steps of porting GWorkspace to Mac OS X. I do this 
mainly to make some more developers interested in this project and to give 
Apples Finder (which is a Carbon App) some competition.
At first I created a Project Builder project (.pbproj) and added all the 
sources as Folder References. Then I tried to build the thing.
Here I had some troubles with the macros RETAIN, ASSIGN, RELEASE, TEST_RELEASE 
and AUTORELEASE since those don't exist on Mac OS X.

My Question is now:
Where do I define such macros (new headerfiles?) and how do I include them 
into the source?

Then there was a discussion about porting GNUMail.app / Pantomime to MacOS-X on 
the list some weeks ago:

is this the way to go?

And finally the output the compiler produced when trying to compile 
GWorkspace:
