Cool!

I was now able to take GCJ for a spin on the Rexx to native
test. GIJ works(see bottom), but the GCJ compiled code crashes. 

Thought I'd post the results, in case it has some value w.r.t.
GCJ 3.3 betatesting.

Example of GIJ working...

C:\temp\rexx>java -cp netrexxc.jar;.;rexx2nrx.jar qtsmall
It's almost eleven o'clock.

C:\temp\rexx>\thisiscool-gcc\gcc-3.3\bin\gij -cp \thisiscool-gcc\gcc-3.3\share\j
ava\libgcj-3.3.jar;netrexx.c.jar;.;rexx2nrx.jar qtsmall
It's just gone ten o'clock.
