The problem with this construct is that it is not portable.  Many
machines (read 68000) require integer data to be aligned.
Actually, i have in my "standard library" of home brewed routines:

int intat(p)
unsigned char *p;
{
	int x = 0;
	x = (int)(*p) * 0x100;
	x += *++p;
	return(x);
}

long longat(p)
unsigned char *p;
{
	return(((long)intat(p) * 0x10000L) + (long)intat(p+2));
}

/* Please note these are from memory, I think I handled sign extension woes
   but these are just skeletal for the idea */


Actually, these two routines aren't even completely portable because they
assume a big-endian architecture.  The would have to be rewritten (or ifdefed)
for a little endian architecture.
