Background:
I want to construct a portable Makefile to build a java application.
When a java source file contains an inner class, it creates class
file names with an embedded '$'.
$ cat foo.java
public class foo {

Dear Jason,
I want to construct a portable Makefile to build a java application.
I've played with Java and Make in the past, but I found that spawning a new
instance of the Java compiler is more expensive than compiling a pretty big
bunch of files. gcc starts up a lot quicker than a JVM.

They may be read-only if you're running with securelevel 0. Otherwise they
