That isn't a simple one line fix though. :-)

A brief glance suggests that it may not be that much more, but that
there are subtle differences in behaviour.
Interestingly enough, libjava and fastjar appears to have moved in the
other direction in 2002, for the latter as part of cross-compiling support.

How about starting off with the simple patch to fix the broken macro?

There should be no bad effects of this bug for current 3.4.
