I suppose the reason gcc is set to flag these as warnings is that it is
not all that good a programming practice to call functions like fgets()
or fgetc() and ignore the return value.  The main function of the return
value is to check for EOF on the input file, and do something reasonable
with that information (like return an error upstream).  But that
requires more coding than just a one-line fix; it may require some
restructuring of code.
