   Thanks to the combined efforts of reasonable quantities of alcohol and
   several people who know significantly more about this sort of thing than
   me, it now works. /usr/include/sys/stat.h rewrites fstat() to
   __fstat13(). The fstat() in libfakeroot therefore gets rewritten to
   __fstat13(). The fstat in libfakeroot calls fstat() in libc, which simply
   calls __fstat13(). Sadly, since libfakeroot is LD_PRELOADed, this calls
   the libfakeroot version. Which calls fstat() again. Altering libfakeroot
   to call __fstat13() rather than fstat() makes things work, but this is
   likely to break if the version name changes again in the future. I'm not
   sure what a more long-term fix is.

hmmmm.


there are lots of versioned system calls.  i'm sure this really
affects more than fstat().  the others probably just cause less
drastic (but potentially more dangerous!) lossage.
