So obviously before I joined the project :-)

BTW, I've found some other objective C functions in the StepTalk  
source (and as a matter of fact in Jigs as well), namely  
objc_sizeof_type, objc_alignof_type, and objc_skip_typespec, which  
also are not part of Apple's runtime. Looking at GSObjCRuntime.h, it  
looks like we don't have runtime independent replacements for these,  
do we?
