This is OK, except...

... this is printing/calling a function, not a variable:

 (gdb) print g0 ()
 'g0' has unknown return type; cast the call to its declared return type

So the git log and ChangeLog are inaccurate and should
reference 7022349d5c86 ("Stop assuming no-debug-info functions
return int") instead.

OK with that fixed.
