Apple specific options: patch to include them in the current release gcc?

One thing to remember is that most compilers (visual C++ I know is like 
this and probobly intel C++, OpenWatcom, Code Warrior etc) operate at the 
ASM level directly as the last pass and can figure out from studying the 
inline ASM itself what registers, local variables, global variables etc etc 
it needs to reference.
But GCC isnt able to do this so you have to tell GCC yourself what 
resources a given block of inline assembler accesses.
