Actually, the history check uses:
if (linemap_location_before_p
(line_table,
context->classification_history[i].location,
location))
and that seems quite smart about how to compare things. Perhaps if we force
input_location to point to foo, things will work as expected. In any case, no
for GCC 6 and there are probably many cases where this won't work because we
don't have a location for 'foo' ( e.g., C(1) ).
