Some news of my overlay

I added
	* shell wrapper scripts for java{,c,doc} to reflect gij / ecj / gjdoc
	* symlinks to jar, javah, rmic (from fastjar, gcjh, grmic)
	* java-config-2 integration with java-config-1 compat
	* PDEPEND on eclipse-ecj and gjdoc

to provide a usable JDK with dev-java/gcj

I also added a Ecj Compiler Adapter and GnuRmic Rmic Adapter
to ant-{core,tasks} which need review. They seem to work.
It is simple code.

Azureus, Beanshell, eclipse-sdk, Xalan and dependencies merged
without issues. OpenOffice.org will need some tweaking for gcj / ecj.
Luckily there is a hack from Arklinux to base the work on.

My todo
	high priority
	* fix issues that pop up (OOo, ...)
	* wait for java-config-2 to get into Portage

	medium priority
	* integrate jar to native

	low priority
	* eclipse-sdk to native

I really dislike that java-gcj-compat.
Why? I used it. It is extra work you just do not want.

I just do not want to see it in Gentoo! ;)

Would be a cut and paste from dev-java/gcj then.

That would be the database / jar to native work as planned.
I use 'native (nativeonly)' useflag for eclipse-ecj and gjdoc already.

True.

We got java{,c} for standard JDK behaviour.
I add 'native' useflag to get native code.

There will be issues, for sure.

I set one way to go.
It just needs to be accepted or tweaked to your liking. ;)
Finally, one needs to write the code.
-> which is me
... and maybe some Java programmer
that got some extra spare time to waste?
