Hi,
We need to know when fgets() returns with error or end of file, but the
assignment approach deprives us of such information. Also, the fix
properly handles the unnecessary warnings. What a deal!

As no error was handled, we wouldn't be able to know when an error does
occur. The fix preserves error messages while it doesn't let unnecessary
compiling warnings show up.
