This BYFOUR code accesses the passed unsigned char * buffer with a 32-bit
integer pointer type. This violates the strict aliasing rule, where a
compiler can assume, for optimization purposes, that two pointers to
fundamentally different types won't ever point to the same memory. This can
manifest as a problem only if one of the pointers is written to. This code
only reads from those pointers. So long as this code remains isolated in
this compilation unit, there won't be a problem. For this reason, this code
should not be copied and pasted into a compilation unit in which other code
writes to the buffer that is passed to these routines.
