[Q] Porting StepTalk to Mac OS X(ObjC Runtime Compatibility)

[Sungjin Chun]

Hi,

I've try to build StepTalk on Mac OS X using Cocoa framework. And I 
found that StepTalk depends on GNU ObjC Runtime and this makes porting 
somewhat hard.
Now, here comes the first question:
1. In StepTalk code sel_register_typed_name, but Mac OS X or NeXT ObjC 
runtime does not have this one, instead, it has sel_register_name only. 
Can I use this function instead of GNU's one?
2. +[NSMethodSignature signatureWithObjCType:] is used in StepTalk and 
I found that this method is Cocoa.framework although hidden. Can I use 
same argument for this method, ie., type is compatible?

Thanks in advance.
