Description: Fix some compiler warnings.
 Also check the return value of fread/fgets.
 .
 comparison of distinct pointer types lacks a cast
 assignment makes integer from pointer without a cast [-Wint-conversion]
 'main' is usually a function [-Wmain]
 'foo' may be used uninitialized in this function
 missing braces around initializer [-Wmissing-braces]
 passing argument N of ‘foo:’ from distinct Objective-C type
 passing argument N of ‘foo:’ from incompatible pointer type
 initialization of ‘double *’ from incompatible pointer type ‘id’
