Interesting point. I could imagine that a "static" function, which is by 
definition not visible outside the object file, will have its "static" 
local variables initialized on a per-object file basis. For non-static 
inline functions, if the compiler needs to produce code (because maybe 
it cannot inline some of the calls) there has to be some logic that at 
most one version of the function is linked into the executable. The 
static local variables should be handled in the same way.

However, this is indeed a rather tricky detail of the language 
definition, so I it might be worth checking the compiler. In this case, 
however, it will not affect the correctness of the program.
