You need to use fscanf(file, "%c%c%s%*c", &flag1, &flag2, line);.
The asterisk is mentioned on page F-100 of the Lattice 4.0 manual, under
the fscanf/scanf description.  It says that the conversion is to be formed
(reading the next character) but the result not stored.  It snarfs up the
whitespace (blank, tab, or newline) that terminated in string read in by
the previous "%s".
