eclipse, jamvm, and classpath

[Tom Tromey]

Thanks to Rob, now that jamvm is in CVS, it should be much simpler to
set up a trivial-to-use classpath development environment in Eclipse.

Appended is a patch to eclipse-ify jamvm and to make it work nicely
with classpath.  It has 3 parts:

1. A small Makefile patch to make it so that you can compile against
   an unzipped classpath; this is used with --disable-zip.

   I took a minimal approach to fixing this.  There are a couple
   other potential Makefile changes in this area:

   * Use real automake conditionals
   * Allow use of compilers other than jikes
   * Ultimately, add a special eclipse flag so that the java source
     in jamvm is compiled inside eclipse with no external build step.

   I didn't include the diffs to the auto*-generated files.  I have a
   different version of these tools anyway...

2. Addition of a lot of .cvsignore files.  This is just friendlier
   when making patches and whatnot.

3. Addition of the eclipse build goo.  I have set things up so that it
   simply assumes you have checked out classpath into your workspace.
   And, I set it up to use this classpath by default.  That is, this
   is not a generic configuration but instead a way to make it very,
   very simple to run jamvm against the classpath you are developing.

To try this out:

* Check out classpath in eclipse and build it
* Check out jamvm in eclipse
* Apply appended patch, re-run auto*
* Build jamvm in eclipse

Now the jamvm in <workspace>/classpath/install/bin should work just
fine.  If you edit a java file in classpath, eclipse will rebuild it,
and jamvm will immediately see the change.

I have a patch kicking around to show how easy this really is; it adds
a launch configuration to the visual tester so that you can literally
go from a classpath change to running the test with a single mouse
click.
