Can't build simple program

[Mark K. Gardner]

I built the simple "Hello World" program as per the instructions on
< http://sourceware.cygnus.com/java/gcj.html >. Now I am trying to build
a slightly more complex program and I get a link error which doesn't
make much sense to me. What is `_CL_8HeapTest' and how do I make sure
it exists? (The program runs just fine with JAVAC and compiles just
fine with TOBA.) Any help illuminating my understanding would be
greatly appreciated.
