Buildable only?

Hello Andrew, hello Bryce,

For details see my bug reports around 09.Feb.2005 (AWT/19838..19862).
Back then I tried several gcc-4.0.0 snapshots, the latest I really
tortured now is gcc-4.1-20050424.
All of this on my SuSE 8.2 and 9.1 systems. I guess that the actual 
crashes are due to GTK/libpthread problems, not due to gcc/gcj itself.
Here is what Tom (Fitzsimmons) wrote me back then:

Seems that I am not the only one who has problems with GTK...

However, my point today is that even *without* the annyoing-and-hard-
to-debug-actual-crashes, *none* of my (rather simple) AWT/Swing-based
apps would be usable with gcc/gcj.
>From my point of view, it is very hard to understand that you keep
adding fancy compiler options (like gcj-dbtool or gcjx), while even
pretty simple applications don't work at all - as soon as they use
AWT or Swing. I admit that most of the java.lang, java.math, java.io,
java.net, and java.util stuff is pretty good already, and from what
I've heard some of the javax.* things are good, too.

Just out of curiousity: during the Cygnus times, gcj seemed just like
a small and fun project to me. But now that Redhat is quite a big player, 
and gcj the biggest partof gcc (using either LOC or build-time as a metric), 
isn't there any way that Redhat can spend some of the IPO money on 
a few man-months of full-time AWT/Swing development?
