You have _giant_ inline functions here, why?

Please just put this all in a .c file and let the linker properly handle
things. You do not want to duplicate all of these crazy strings all
over the place where ever you call these functions.

And I am guessing this is only for some sort of "debugging" mode? If
so, shouldn't there be a way to not even build this in? Some systems
are very space constrained...

thanks,
