The error is actually not as bad as that (well, actually it's a
warning, but it's got treated as error with -Werror).
It's because the printf() argument doesn't match the format string.
Something like this:
long lval=0;
printf("%d\n", lval);
With the printf() above gcc will complain that the format ("%d", an
integer) doesn't exactly match the argument (a long int). The
solution is either to change the format to long int ("%ld"), or to
typecast the variable to int, or to disable -Werror, for now.
