Did you compile with some optimisation? I think I remember that gcc
only inlines code with optimisation turned on.

I think it makes sense to use

`always_inline'
     Generally, functions are not inlined unless optimization is
     specified.  For functions declared inline, this attribute inlines
     the function even if no optimization level was specified.

here, i.e. __attribute__((always_inline)). I personally prefer inline
functions over macros.
