-one portable way around that is to do something like:
-
-	typedef char *caddr_t;
-	typedef union {
-	    struct { int t[512]; } t512;
-	    struct { int t[256]; } t256;
-	    caddr_t               caddr;
-	} ustruct_t;
	...
-	    if (n & 512) *dst.t512++ = *src.t512++;

`Portable'?  I suggest you try it on a Data General MV/10000.
