$ gcj HelloWorld.java
gcj: libgcj.spec: No such file or directory
The gcj FAQ (entry 4.7) says:
Make sure you configure both libgcj and gcj with the same "--prefix"
However, the gcc-java nor the libgcj package seem to include the
libgcj.spec file at all.
*** Bug 15349 has been marked as a duplicate of this bug. ***
Should be fixed in libgcj-2.96-21
