What's wrong with the atomic macros already existing?

http://www.nongnu.org/avr-libc/user-manual/atomic_8h.html

A function call is rather heavyweight for something as simple as locking 
interrupts.

As the above macros require C99, Teacup Firmware created a similar macro 
set working on C89, too:
