Commit a preview of osx386 and osxppc as new platforms. These produce Mach-o executables for Mac OS X on Intel or PowerPC processors. Our code generator for PowerPC (mach/powerpc) still has bugs. Some examples seem to run, but startrek crashes. Our code generator for Intel (mach/i386) is better. There is a problem with job control. If you run paranoia or startrek, then suspend the job (^Z) and resume it ('fg' in bash), then read(2) might fail with EINTR.
