It may be more important to examine what compilers/optimizers that you 
have available to you.  Each company, e.g. HP or Sun, makes their best 
effort to optimizer their native compilers for their CPU architectures, 
e.g. PA-RISC & SPARC, and this will certainly have a large impact on 
the size and speed of the generated code.  Maybe larger than the actual 
differences in the source code and the subsequent method invocations 
and function calls.  These native compilers support C & C++, however 
(to my knowlegde) no Objective-C.  Therefore using the GNU compiler on 
such a machine may slow you down even if you are using plain old C, not 
to mention C++ or Objective-C.  Take a look at what the different tools 
have to offer (if you have a choice that is).
