Problems Compiling Kawa 1.8.91

[Tony anon]

I have no problems compiling Kawa 1.8 on Windows using Ant.

However, when I try to compile 1.8.91 I receive the following errors.  They 
all appear to be confined to two files: XMLParserChar.java and 
XMLParserByte.java.  Any help would be much appreciated.

I'm running the following:
Windows XP SP 2
Java SDK 1.5.0_09
Ant 1.6.5

Output from Ant:

Buildfile: build.xml

build-tools:

build-settings:
     [echo]
     [echo]         version=1.8.91
     [echo]         dist.kawa.jar=D:\Temp\kawa-1.8.91/kawa-1.8.91.jar
     [echo]         build.dir=D:\Temp\kawa-1.8.91
     [echo]         with-awt=true
     [echo]         with-swing=true
     [echo]         with-sax2=true

     [echo]         enable-xml=true
     [echo]         enable-servlet=false
