+ *
+ * Note that the "buf" pointer in memory is probably unaligned.

+ * Were these functions to be re-written to take a 32 bit wide or 16 bit wide
+ * memory access shortcut, then on some CPU's, i.e. ARM7, the 2 lsbytes of the address are
+ * ignored for 32 bit access, whereas on other CPU's a 32 bit wide unaligned memory access
+ * will cause an exception, and lastly on x86, an unaligned "greater than bytewide"
+ * memory access works as if aligned. So what follows below will work for all
+ * platforms and gives the compiler leeway to do its own platform specific optimizations.
