With 32-bit micros you very seldom use special C constructs - like 
you would with 8-bitters. For the most part, the C extensions in 8-
bitters are there because the 8-bitters cannot run normal C 
efficiently or to do things like support bit variables (like you get 
in 8051). For "grown up" CPUs like ARM, you don't need these 
extensions.

I prefer to keep all my C code completely clean of any "special" 
extensions. This allows the code to be tested in PC test harnesses 
where possible and allows the code to be reused easily across 
projects.
