Unfortunately, I cannot see any way to know that FOO is a constant that comes
from an enum. Joseph, is this possible to do in the C FE?
Also, constants don't have locations in GCC, so no way to know that it comes
from a macro. Sorry!
This a problem also in G++, but in this testcase it doesn't trigger because arg
is considered to be signed. I guess it can trigger in other testcases.
