Yes, but that would not help my intention of making the file more
generic. The x86 code was copied into a number of architectures, and
at least arm, m32r, parisc, sh and xtensa have big-endian configurations
where the implementation is wrong.

I only realized that while writing this email though and I guess I
need to fix those as well now ;-)
