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 ;-) Arnd <><
