you are perfectly right, but suppose you have to write a qsort callback:
void qsort(void *base, size_t nmemb, size_t size, int(*compar)(const
void *, const void *));
suppose the "const void *" is actually an int value. By downcasting it
to int, gcc gives you a warning.

longjmp() and setjmp() are useful for dealing with errors and
interrupts encountered in a low-level subroutine of a program.
We have implemented an exception-like environment in standard C so we
need them.
