Well, truth is, the Makefile works as intended, the way it was written. 
It was never intended to be executed in place; instead, it was intended 
to be bundled with the javac source files, as part of the initial 
compiler-only release. In the bundling process, it gets "moved" to the 
correct place (the root of the bundle) so that it all works as 
expected.  The only reason the src/share/opensource/javac directory 
continues to exist is to support that same source bundle in the form 
that people have been used to, while other churn continues, hopefully 
for not too much longer. Eventually, src/share/opensource will go away

With respect, we already have too many build systems: 4 public ones (the 
main JDK Makefile, the November compiler Makefile, the November compiler 
build.xml, and the new OpenJDK build.xml). In addition, I have a couple 
of additional private legacy build systems for some projects that 
predate the OpenJDK work. So that's more than a few too many. I would 
like to get this down to one build system, and while I don't expect JDK 
to move to Ant wholesale any time soon (if ever!), I think it is 
reasonable to consider the compiler and related tools using (just) Ant.

As for that hairy OpenJDK build.xml file -- yes, it's hairy. It's on the 
list to be rationalized/simplified/cleaned up. We've started making a
