Building classpath with ecj

[Trevor Harmon <trevor@xxxxxxxxxx>]

My understanding is that the latest release of classpath can be built  
using ecj. This is not working for me, however. My configure settings  
are:

--disable-dependency-tracking --disable-gtk-peer --disable-gconf-peer  
--disable-plugin --enable-jni --with-ecj-jar=<path to ecj.jar> --with- 
vm=java

But I get an error during build:

$ make
Making all in lib
true
top_builddir=.. top_srcdir=.. /bin/sh ./gen-classlist.sh standard
Adding java source files from srcdir '..'.

This is with classpath 0.97.1, ecj 3.2.2, and Java 1.5.0_13 on Mac OS  
X 10.5.2.

I tried changing the memory option from "-J-Xmx768M" to "-J-Xmx2048M"  
but I still got the same error. Surely 2GB is a large enough ceiling  
for the build. And my machine has 4GB RAM, so I don't know why I'm  
running out of heap space. Any suggestions? Thanks,
