Yeah, some of them.  But thanks for pointing this out since now I
realize I forgot to put "check in test suite .jar files" on my to-do
list.

Also, naturally, we have to fix these before a merge.  So I suppose
there is a lot more to do yet :-(

Gary>   FAIL: ArrayStore output - source compiled test

There's a PR for this one.  The code implementing this in gcj looks
wrong... and furthermore looks to have been wrong for a long time.
Kinda weird.

Gary>   FAIL: PR162 output - source compiled test

Haven't investigated but I'm seeing it as well.

I also see:

FAIL: natshortfield.cc compilation
FAIL: register2.c compilation

These look like some failure to generate a header file -- test suite
problem, not gcj bug.

Gary>   FAIL: Process_4 -O3 compilation from source

I don't see this.

Gary>   FAIL: Serialization execution - source compiled test

I see this but haven't investigated.
