The expression
	
	((int *) c)

is not a modifiable l-value.  It is the value of the variable "c"
treated as a pointer to an integer.  If you want to modified what
"c" points to, insert a "*" before it.  That is,

	*((int *) c) = &(buf[0]);

The result of a cast is not an l-value.

If you want "c" to contain the value of the address of the 0-th
element, you must do something completely different, like the

	c = (char *) buf;

example that you gave, or possibly

	*((int *) &c) = &buf[0];

which will do something similiar (only different ;-)
