Kawa build problem

[Chris Bitmead]

For some reason kawa doesn't build because the CLASSPATH ends up with a 
":" at the end in gnu.xml package.
Why this is a problem I don't know but it's illustrated by the 
following. Note the 2nd case the CLASSPATH is different and it fails.

Chris@TARDIS!603!bash:/cygdrive/c/downloads/kawa-1.6.99/gnu/xml$ 
CLASSPATH=../.
.:./../.. javac -d ../.. NamedChildrenFilter.java
