Building Unix Squeak VM On Intel Mac

[John M McIntosh]

Clues for other are:

usage of

     register char* localSP SP_REG;
     register char* localIP IP_REG;
     register sqInt currentBytecode CB_REG;

versus

     char* localSP;
     char* localIP;
     sqInt currentBytecode;

which confuse and cause gcc 4.0x to crash. Also to produce poor code,  
in checking removal of this gcc hack produces better
code on intel for gcc 4.0x and powerpc on gcc 3.3.  Likely one should  
also visit compiler options on xcode project to understand the choices
I made which seem to make better assembler since we don't have to  
support legacy hardware.
