Hi Matthew,

sorry, but this is a real bug: 'nm' shows that GCC looses completely
*the definition* of the function which is in fact present in the source file
and as a result you get an unresolved reference at linking stage.
It is not a matter of inlining or not inlining a function, it's a matter
of *loosing* it's body.

Regards, Pasha.
