One example is that I want to use some macros inside the embedded c 
functions in my stp files:
function foo1()
%{
    _stp_printf("%d, %d...", EVENTID_1, HOOKID_2, ...);
%}

such macros appear almost in every stp files, so it's better to 
include a .h file in each stp file:
%{
#include "macro_defs.h"
%}

But the problem is that if macro_defs.h is put into the place other 
than /usr/local/share/systemTap/runtime, stap can't find it.
