This is some conflict between the new binutils and UPX.  Someone 
needs to diagnose the problem and provide a fix (either to the
UPX maintainers or to the binutils maintainers).  This problem has
been discussed on the djgpp-workers list, but no one has both the
time and motivation to track it down and fix it.

I'm personally very unhappy about this (if it were me, I would 
continue to use the old binutils because of this) - but whoever builds
the packages gets to decide which toolkit to use.
