assign - assign an integer value, check for truncation
#include <libowfat/rangecheck.h>
int assign(dest,a);
If a and dest have the same type, or the value of a is representable in the type of dest, do dest=a and return 0.
Otherwise, return 1.
Note: This is a macro, so dest does not have to be a pointer.
In the multiplication functions, a return value of 1 signals success and 0 failure. In add_of, sub_of and assign it's the other way around.
