> Do we ever intend to create a warning for FERROR?

Probably not (but there may be some not yet modeled stream operation where this 
may be useful.). This is when FERROR is set but not the indeterminate position. 
It indicates that the last operation failed but it is OK to use the stream. But 
this can be a "ErrorReturn" checker problem (a failed operation was not 
observed by the program).
