Anyone here already working on fixing that feature?

I'm too new myself to know how socially correct C code in linux does
distinguish big-endian from little-endian.  Perhaps the first fragment
that leaps to my mind is:

static inline int lil() { int const i = 1; return *(char const *)&i; }

I'm too new to have tried that fragment in many gcc and linux.  I would
be disappointed, though not really surprised, to discover that the gcc
of wherever we see udf disks in fact doesn't support that kind of
constant as well as a #define constant.  Could be that an initialised
const union of char with int might work better.
