Did you compile with some optimisation? I think I remember that gcc
only inlines code with optimisation turned on.
No -- the Makefile is used as is -- you're the one modifying things... ;-)
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.

Well, I don't have that personal preference, ;-) and after making it a macro,
it works as expected. At least with the macro, I *know* what's going to
happen...
