"wmemcmp is widely available but is based on wchar_t so is for different widths on Windows and Unix. On Windows it would handle the 2:2 case."
I don't know if wmemcmp() can be used if wchar_t type is signed. Is there an OS with signed wchar_t? If yes, we need to check if wchar_t is signed in configure.
On Windows, wchar_t size is 16 bits, whereas it is 32 bits on Mac OS X and Linux (and most OSes).
