A fatal_error occurs immediately.  gfc_error actually 
writes the error message to a buffer and gfortran 
will continue (usually by backing up) to try parsing
a potentially different code route.  If the new code
path is successful, the error message is discarded.
If the new code path fails, another error messages
is written into the next buffer location.  If gfortran
fail determines that an error has indeed occurred, it
will then write an error message from the buffer(s) to
stderr.
