    So, just putting the function definition after tyhe function call is not
    enough to prevent inlining.  Too bad.

This shows the function was not discarded.  If it is not static, it
cannot be discarded.  But this does not tell us if the function was
actually inlined.  It might have been inlined *and* compiled straight.

The only way to tell if it was inlined is to look at the compiled code
of x_error_handler and see if it calls x_error_quitter.
You could do that by using x/i in GDB.  First do `x/i &x_error_handler'.
Then x/10i will print 10 more instructions, each time you do it.

Andrew, could you try that?
