I'm not convinced by the following:

The first time we hit the function, sym->resolved is set to 2.
Suppose that an error is issued, and the function returns false.
Then, on the next time the function is called with the same symbol argument, no
error is issued (this is the purpose of the patch), but as a side effect the
function will return true, so that the caller will proceed as if the symbol was
well formed.
